Update-grab a snack lol

Hey ladies! I hope you are all doing well. I just wanted to update you on what has been going on.
No we were not married (I said we were cause people on here can be judgemental, sorry for lying). We were together for 6 years and engaged for two. So he ended everything because he never dealt with his feelings on the abortion (and kept his feelings buried) and with everyone having kids around us and us trying to conceive he just lost it. He thinks he is the reason we didn't get pregnant but he never wanted to get tested. I ended up moving out of our apartment together and he bought the home we were supposed to purchase together. I now have my own apartment (but I'm to lonely to stay there, I sleep at my sisters). I found out after we broke up that he was on tinder (dating/sex app). I asked him about it and he said he's numb and just doesn't care about anything anymore. The person I feel in love with is gone, it's like he's broken. I know he didn't cheat, he's definitely not that type of person but I know how this looks from the outside.
I have been going to therapy once a week but I am still having a very difficult time with this. I feel like it's all my fault and he will move on and be happy and I'll be alone. I will say since we broke up things haven't been going his way, just bad luck and karma I guess? 
I would love any insight or advice from you ladies. If you have questions just ask, even though I'm not ttc anymore I still enjoy talking to you ladies and getting your advice.
