Feelings hurt...

Jessica
So my ex and I have been separated for about 5-6 months and I'm 32+ weeks pregnant and I found out that around the time we found out u was pregnant he was talking to another woman. I'm not going to lie I read his message and journal that while we were together even during intimate moments he was thinking of the girl and all of last year he just talked shit about me, had nothing good to say about me after I've sacrifice myself for him... Completely put everything into him where I had no live left for myself. I know he'll never admit to it but I'm very hurt bc even now I've been helping him with getting to work bc he had no car... I figured if I sees that I still care maybe things will go back to bring happy but it seems like he was miserable the whole relationship. I feel like an idiot letting him drive my car to work and thinking dinner part of him still care or love me but I feel like I was poison to him. Should I stop helping and move on? But stay in contact for the child?
