😥Cheating spouse!

So please if you are a negative Nancy do not comment, I am too emotional for the negative comments!

I really need help my husband cheated a year ago & I became pregnant 3 months after he cheated honestly I didn't have time to process the infidelity.

Back story: my husband's ex came to town to see him (they both said they were only talking 2 weeks before she flew in) So he was out of work and I was taking care of home which was okay giving his circumstances but he cheated the weekend of our (over 5 year) anniversary. He told her so many lies on me/ about me like I always nag, he's not happy, he's only here for the kids.. she told me everything. We literally don't argue, we talk through things, I just didn't understand at all. He slept with her unprotected.. the list goes on! I feel so out of place and don't want to be with someone that I'm not truly making happy. I want my husband to love and adore me. I don't want to be the last option. We went to counseling as he asked because he wanted his family but I can't help but feel he's not truly happy. I feel like everything he tells me is a lie. I don't believe anything but we have other kids that love him so much so I just don't know what to do. I pray and pray for God to help me but I am f'n losing it. I have no one to talk to because everyone feels like it's just cheating it's normal get over it! I'd rather be alone before I continue to be this broken! Please give me some good advice!
