This is incredible to find this. I thought I was crazy for how I was feeling and what I was going through.
I was with my boyfriend for a little over a year. And it was on the SAME timeline as you. Every 2 months or so it's a breakdown. He feels nothing. He's cold, breaks up for no reason. The 2nd time he did this... he actually left to date other women. Slept with a few. Afterwards came back saying he realized what he had and would do whatever he could to fix it. For another two months he was an amazing boyfriend. Crazy about me - so caring. I came first, so did my feelings and our "family" with his 2 year old son. about two months-3 months later.. breakdown. This was brought on by some dramatics with his ex wife, but once again just... shut down. He comes back a month later saying he can put it all behind him and he was so thankful I was still in his life. Exactly about 2 1/2 months later... shut down.
Literally... right before my eyes I saw the shift. All night he kept asking me for kisses. Dancing with me happy in the kitchen. Cuddling up with me. Just LOVING on me. Then he saw what time it was... seemed irritated that he was up this late... and the affection left. Wouldn't touch me. Wouldn't kiss me. Wouldn't hold me. This went into the morning. Then he disappeared for two weeks. Just yesterday he finally broke it off saying "I dont know, my heart just isn't in it. Maybe you arent the right girl for me, and i should date and see other people". Just... snapped. Right before my eyes. And it wasn't just a break up, the man was yelling at me, coldness in his eyes like I meant nothing to him.
The worst part is that this man is pretty much the sole parent to a 2 year old boy. I've been called family. Taken on a huge role in the boy's life as a mother figure as his mom only comes around 2 weekends a month for a day or so. And each time he does this he takes me from the boy.
The worst part is even though he is gone again and so horrible and cruel... I am hoping he comes back. And hopefully is back into that place of clarity to be able to reason with him to really get himself help if he wants to be with me. Reading this story reminds me so much of mine. It's so confusing. But maybe he really does have a mental condition. Add in that he is in the process of a divorce.
