Did anyone else get discarded during a very emotional/painful time in their life? (TW)

(TW) I got discarded by him a few days after Christmas, the day I was getting an abortion he pushed me to get and didn't pay a dime for. And that happened after he specifically promised not to leave me after my abortion, as I had feelings he would. He also admitted to having manipulated me for days before by promising he would change and apologising for the things he did to me up until that point so that I would for sure get the abortion. I don't know how one is supposed to trust anyone ever again after such an event, especially since I predicted what would happen, but chose to force myself to believe him as I didn't want us to argue again over my trust issues (which weren't for no reason and I ended up being right about almost everything). I just don't understand how they have no sense of responsibility at least, let alone empathy. It's mind boggling.
