Narc back trolling online dating sites

Okay well narc decided to continue texting me and acting all caring and concerned I been brushing him off but keeping him around cause I still have feelings for him. When we first met he said he wanted to be in a relationship with me mind you we met on a dating site Pof back in March and been dating since he has been acting strange too so today I decided to Google him I found him back on the site where we met saying he looking for relationship and single and describe his ideal relationship I didn't know rather to laugh or cry because I know hefull of crap. My mind is spinning and thoughts come in my head maybe I wasn't good enough or I'm dumb to even talk to him I should of kept Nc well today he text me and I deleted his text and finally blocked his number this was the last straw I feel sad for the next victim but at the same time I'm glad I looked I would of thought he geninuely cared and was going to change lol what a shame. I know now he is disordered and can't help himself but to Lie and create a false facade for his newest victim's.
