Lemon's question on blocking

Hi Ladies,

(a VERY short version of my story:)

I was introduced by a mutual friend, then talking for a month, then seeing my exN for 5 months, supposedly quite exclusively. (I did ask all the right questions and make it quite clear from the beginning that I only wanted an exclusive relationship. He agreed and repeatedly lied through his teeth.) Two days before we were leaving on a two week roadtrip to move him to his new state together, I, by chance, came to find out that I was actually the unpaid mistress, (even though he was telling me he was deeply in love with me, soulmates, wanted me to move out of state with him to build a life together, blah, blah), as he has had a girlfriend for the past 15 years and he's been living at her place the whole time, (and recently, somewhat at his mother's, which is where he told me he lived). He was right there when I put his gf on speaker on his cellphone. He wouldn't say a peep, so she wouldn't know he was actually there...she kept saying I was lying and that I had stolen his phone. When I got off the phone, he was looking through my fridge as though nothing had happened. I looked at him and said, what the hell (or something like that)...he very blasely, calmly, and upbeat-like says "Well, you had some new experiences:)"...like this is all perfectly fine and I should actually be kinda happy/lucky/grateful!?!. (Actually, he is broke, but acts like he has an exotic, successful business, and did nothing for me or my life.) At that moment, it flashed through my mind that he was a sociopath. I told him what I thought of him and kicked him out out my house. Btw, he and I are both late forties, never married, no kids, grad degrees. I have been NC with him since, which is over 3.5 months. He has VERY VERY many times called, written long nasty emails and texts, and stalked MY social group and functions, and is spreading lies to and garnering sympathy from some of our mutual friends and acquaintances. He writes the most bizarre and nasty stuff...(and only now after getting dumped) criticizing my looks, my age, my reputation, my friends, my townhouse (that he spent our whole relationship at), my family, etc. He says I'm having one night stands, and am an alcoholic...his latest is that I have Fetal Alcohol Syndrome. It's all crazy and untrue, not to mention completely irrelevant to the issue at hand of our breakup...and btw, I was 100% faithful and great to him during our relationship.

I have not responded at all to any of his contacts. And, believe me, he has tried every angle. Among other things, he said that "I really blew it because he had planned to ask me to marry him at (a special place) on our trip to his new home...and that we would work together in his business and build an incredible life and he would have given me everything I had always dreamed of...", etc. When he came up to me twice at a party, I said I had to get a drink and bolted away. I haven't talked about him to our friends, either. He's also been threatening to ruin my reputation with MY social group (which he is now driving an hour to start going to parties (he never was in/at the group before) and schmoozing up to the male leaders of it and Facebooking them).

Anyway, it's been over 3.5 months since I dumped him and have been NC. Except, I just came to realize that maybe I haven't been NC enough, because I have been reading his looong emails and texts. I am really sick of all the really nasty stuff he says...that is bizarre, untrue and that is completely irrelevant to why I dumped him (blameshifting, projection, deflecting, triangulating, nlp, gaslighting...I know!)...but yet hurtful (says I'm old and wrinkly and fat and desperate, etc...I'm not!) I guess and gets me thinking about him more. He really put me through a ton of lies, punishment, ST, roller coaster, breakups, and me being hurt, stressed, brokenhearted, depressed...during our 5 to 6-month relationship. Oh, and he is also a big user/mooch. So, when I found this out and dumped him, I didn't want him to just go on his merry way, with no repercussions. Well, his ton of long contacts to me over months, have been somewhat of a payback...but I think that it might be best to block him from contacting me via phone, text, email...because I probably shouldn't let him get in my head anymore than he is anyway. Also, I have a lot of other problems in life right now (laid off, financial) and really don't need my self-esteem lowered and my time wasted (any more) by him.

Here's his lastest email&text to me, sent, btw, soon after he saw me in pics on FB (I have him blocked) looking good at a blacktie NYE party in pics with men we know (btw, this email is VERY short for him):

"Well I'm really sorry we didn't meet under better circumstances. I also forgive you for all the ways you sabotaged what could have been incredible, because you couldn't understand. And finally, I do hope you find someone who cares about you as much as I did. You might also prep him with the information found in these links. If he really cares about you he'll study the issues and not be so confused as I was as to how you were acting with me and other people. I'm removing your number and email address from contact list. Good luck, Lemon (Fetal Alcohol Syndrome links follow)

Finally, to my question about blocking:
So, for $1/month I can block his calls and texts. On my service, his call will just ring once, and go dead. So, eventually, he'll probably figure out that I blocked him.
But with texts, he will think his text went through, but I will just be able to see that a text was received, but I won't be able to read it.
With emails, the "block" just actually sends them into a separate folder...so I could actually read them, if I wanted to. (I'm not sure I can trust myself not to read them but I'll try!)

So, I'm wondering if I should:
1) Email to him "Don't contact me again...and I have blocked you and will be deleting any vm's, texts, emails"
2) or if I should block him and just let him think that I am continuing to get/read his messages...
3) or not block and just continue to do what I've been doing...as his contacts have been lessening to infrequent, he said he deleted my contact info and said goodby, and his contacts are not a big deal to me now. He probably has a replacement victim/mistress lined up already...?
4) or ??

Thank you for reading, and for any help with this question and/or situation:-)
