My husband is about to see his ex girlfriend and doesn't know it

Before I get to my real problem that I came here for help, I'll give a little back ground information. First, I'm 23 and my husband is 24. We've been together 6 years and married for 4. We have one 2 year old. In 2014 we bought our first home, and shortly after that things went wrong. He regretted buying the house and took it out on me. I soon found out he was talking to a girl he went to high school with. Turns out he had meet up with her a couple times, as far as I know they only kissed and didn't go farther. But I don't know. We were having problems, we wasn't talking much or doing anything at all. We kept our distance. I begged him to talk to me and he just wouldn't. A little over a month or so later I found out they were still talking and told him either we can work on this or he needed to choose me or her. So he ended it with her. She is not a very attractive girl, so I wasn't jealous of her. At the time I told him to choose, I wasn't aware of the meeting up they did. She also has 2 children. So couple months later, I'm pregnant. And that's when I found out about the meets and the kissing and such. Then his brother lives in Alaska and was getting married so he flew there with his other brother for his wedding. When he gets back, I found out he kissed another girl up there. I'm pregnant this time. So fast forward two years to now. He hasn't talked to any girls but I think about this every day. I have a guard up to him, and I am not letting myself get close to him because I don't want to get hurt again. We don't talk still. We're

Time to get divorced, even if he innocent, I highly doubt it, but even if, you can't let it go. It will only make your life hell.
