I had the same thing happen to me... that guy has huge issues. he's a narcissistic ahole and he victimized you. you are likely a sweet caring person who just finds hope and good in the worst people who mask themselves as normal people but they're not. and no it's not your fault at all for what happened. when I found out the guy I dated for 3 years cheated on me from day one, and fathered 3 kids , 3 kids while he was with me and left a string of other women on welfare I blamed myself! I thought what did I do wrk g why wasn't I enough for him to be with me, but that's how manipulated he's made you. sadly you have to untangle the emotional mess he has left you. it's horrible, it hits your self esteem, I don't know what's real and what's no. what was a lie what was genuine , like you lost your identity in the process ... but I can tell you that you should just assume everything was a lie and I hope you talk to a therapist and get medication. that's what I had to do, even during the process I was so angry, very angry that and depressed that it consumed me, bc I though how could I be like this, taking medication while he's out there living his life with someone knew... but the therapy , talking to someone objective little by little chipped away all that manipulation, anger, loneliness... it happened to me again by with a hug who had drug problems and here I am in my 2nd round ... what I've learned even though I'm still currently depressed is don't bend your standards with men, the first sign of trouble bail , trust your gut instinct bc u don't want to go through this agai . I'm so sorry this terrible jerk did this to you , no one deserves to be treated like that. there's selfish people out there, we need to learn to identify them and stay away.
