Break Up & Divorce

How do you move on after planning your future with someone who changed?

I'm really heartbroken to have to write about something like this but my boyfriend is withdrawn from our relationship 2 months after I gave birth to our first child. He had been going out a lot or hanging with friends or working a lot when I was pregnant but I gave him the benefit of doubt. We argued a lot over stupid little stuff like him leaving the window open or the way I stacked dishes but overall I thought we could learn to communicate-but it started to seem like he wasn't even trying to communicate in a healthy way anymore. Right before the baby was born his brother passed away. I know it hurt him and I was supportive but he seemed like he was turning to smoking heavily, hanging with friends, and coming to me with a forced smile. As my due date approached my frustration grew about him always being gone because I worried I would go into labor and he would be nowhere near. But I ended up needing to be induced so our daughter was born he seemed happy but he still sat out in the car for a while while I processed some of the meds they had given me. All this time I made constant excuses for him, giving him the benefit of doubt or refusing to speak negatively about how it made me feel even though others noticed-even his own mom would comment on how wrong it was When he randomly bought me a car I thought meant that everything was all in my head. Until 2 days ago he exploded on me. He said I was depressing to be around, that he hated coming home because of me and that he avoided me and couldn't wait for my maternity leave to end so he could finally stay home with just him and the baby. So of course I was heartbroken and angry. I tried to process it fast because I couldn't stop crying but I didn't want my baby to see me like that or for me to ignore her need for attention and happiness because of what I was going through. So I quickly swept my feelings into anger and decided to just leave when I have a little money saved up.

I was actually surprised to hear that he thought I was depressing because I had never been happier since the baby was born. his behavior made me unhappy when he was in my presence, and his constant criticism made me unhappy but when he wasn't around I was nothing BUT happy. And despite his behavior I loved him and it was just a rough patch. I honestly thought he was an amazing boyfriend with WAY more good than bad until he said that he basically hated me
