I am about to lose everyone. Religion. Cheater.

UPDATE: Thank you For all the replies! I have actually told my family what he’s done, I told them before I confront him actually because I was so lost as to what to do but they told me then that they’d support me in rebuilding the marriage but not in leaving it. So there’s that.

So. Here’s my crazy story I am open to all advice!

I recently found out that my husband (27) of five years was cheating on me with an 18 year old. I am 37 weeks pregnant and we have an almost three year old together.

He apologized and broke it off with her when I confronted him and says he wants to make us work for the girls etc. he seems genuine enough but after 4 emotional secret affairs this just feels like to much to recover from. I can forgive him, I can coparent but I don’t think I’ll ever trust him.

Which makes me feel like the bad parent because I’d be breaking up my babies family.

Anyway... because the religion I was raised in views divorce and separation as basically a sin. I want to move out (altho with no support and being on unpaid maternity leave that’s going to be super difficult) but if I do I will literally be shunned by everyone in my life, my parents, in laws, friends.

I would be a single mom with a newborn and toddler and no support other than my therapist. I also very much struggle with a few chronic illnesses and depression and I know this situation would make me very vulnerable to my mental health.

I don’t know what to do. I don’t want to be apart of a religion that makes me stay with a repeat cheater, that’s not what I would want for my girls. But idk how I mentally, physically, emotionally, and financially can leave.

What do I do??
