Cheating on pregnant Girlfriend

My boyfriend and I have been together only four months, I am now 13 weeks pregnant. We fell in love fast, it was amazing but we started fighting a lot, about stupid shit.

So, about a week ago I got a weird feeling and went through my boyfriends cell phone not thinking I would find anything but I did.

He was texting this girl.. calling her babe, saying he can’t wait to meet her, he’s totally interested. They called each their “mine”. Ew. The texts went on for three days. While he is texting this girl, I am asleep next to him in bed, also during an appointment for the baby.

I found the messages about a week or so after they had stopped talking. I took pictures of the messages on my phone and I saved her number. I texted her from my phone explaining who I was. She sent me a screenshot of his DATING PROFILE, he messaged her first. I wasn’t mad at her because he never told her he had a girlfriend.

He said sorry about it all and just kept saying he doesn’t want to lose me or the baby and he just wants a family for once not a broken one. For the past week, I have been trying not to think about it but I can’t help it. My heart is broken and I’m not sure if I can get over this and stay with him. I just don’t know what to do.
