Ghost from the past, possible bisexual narc

I will try to keep this as brief and to the point as possible.

I'm a 45 year old single hetero woman. When I was in my early 20s, I had quite a few gay friends and would go to the gay bars with them. After awhile, I became curious about what it would be like to experiment myself. I met a girl, did the deed, and to my shock I ended up "falling" for her. She was engaged to be married, and our relationship continued after she got married. We lived in different towns but I would go visit her when her husband would go out of town. (He was a pilot).  I got the feeling she was only with him for status. She seemed very materialistic and self absorbed. She used to talk about how she planned to send her photos to playboy magazine, and seemed to be pretty full of herself. She never expressed any feelings towards me. I mean in words. She was always very nonchalant and I always felt like she didn't care about me much one way or the other, but I was obsessed with her and thought I loved her. I remember crying over her alot. This went on occasionally for a couple of years off and on. Just every now and again. We finally went our separate ways, and I moved on. That was 20 years ago. I never really forgot about her though.

Since then I've become acquainted with narcissism and psychopathy after several very painful relationships with boyfriends. After I aquired so much knowledge I couldn't help but wonder if she was one too.......But I wasn't sure.

About a month ago I found some pictures of her and I started thinking about her again. It was mainly just pure curiosity of what she was doing now. I thought maybe I would see if I could locate her just to say hi and see how she was doing these days. I managed to find an email address and I emailed her. She called me that very night and we talked for two hours. She divorced the pilot, married another man who she said was the devil and drug addict and addicted to strip clubs. They divorced. She is now engaged to a man (I've seen his picture) he looks very nice but he looks older, he's severely overweight and my first impression is that she's using him. I mean she's still very beautiful, slim, blonde. They don't look right together. Anyway, come to find out, she doesn't work they live on alot of land, horses, the works. So then it made sense. I asked her if she was in love. She said "I don't know, the first year was the hardest."  (I thought that was an odd reply).  So she's been with him 2 years.

Before we got off the phone, she said we need to go to lunch and to call her. I said ok. But before I could, she called me again the following night and wanted to know when my day off was so that we could make plans. It made me nervous! But I went ahead and made plans with her for 8 days later. She lives 2 hours away and the plan was she would leave and get here around noon and we would go to lunch.

The day of our lunch, she called me that morning and said she was on her way. She said she was 2 hours away. I told her to call me when she was almost here.  And I didn't hear from her again until almost 5 hours later. She called and said she was across town at a Mexican restaurant with one of her friends and that she was drunk and asked me if I wanted to come up there. I didn't want to see her for the first time with some stranger there. I told her no I couldn't come so she said we would just do dinner instead and she would call me around 5:00.  And I never heard back from her the rest of the night! I literally sat there drinking and crying all day waiting. 

The next day I was at work, around noon. And she called, but I was so mad I didn't answer. She left a voicemail stating that she was so sorry and that she had had too much to drink and passed out. I did not reply. I was so mad. I waited 2 weeks and then I emailed her telling her how much she hurt me and I told her that she wasted my entire day off and that I had really been looking forward to seeing her for a week and so forth.   Can you guess what her response was? Silence. Nada. Nothing. It has been 3 weeks and I've noticed her posting things on Facebook that seem like they could be directed at me. She posted a quote that said "remember, if someone has a problem with you, it is THEIR problem." Things like that. Like I said it's been 3 weeks since I emailed her, and then today, I discovered that she has blocked me on Facebook. So basically, I'm the bad guy and she hates me because I called her out on what she did. The only thing that makes me feel better is knowing she might be a narcissist and then it would make perfect sense. But I can't help but feel even more hurt that she blocked me for no reason. All I did was try to talk to her about what she did, I wasn't mean in the email. I can't stop thinking about this. I had actually been feeling alot better these last two days until I saw that she blocked me. Do you think she is a narc? How has she got this fiance so fooled? I thought they can only keep that mask on for so long and they have been together 2 years. They look so happy together in all the pictures. But I know she is not  in love with him. I don't even know if she's capable of loving.  If anyone has any insight on this I would appreciate anything you have to say. Thank you for reading.
