My ex boyfriend and I are trying to work things out. His relationship with the mother of his child has been a problem with me because I feel they have no boundaries. For example, while we were in a relationship she would send him sexually charged comments. He would tell me she’s just joking but I don’t find it funny and he won’t correct it. Now today while I was at his house, her car broke down on her way to drop off their kids. She ended up having to stay the night. At 12 o’clock in the morning, he is alone in the guest room with her for almost an hour. It upset me and I told him that but he didn’t think it was a big deal. Am I overreacting?

They were probably just chatting about their kids. You should be able to hear everything going on in the guest room.
You are never going to be able to get rid of his kids mother.
I do have a problem with him brushing off your feelings about this. However, it may just be the way she is and she may bare no ill intentions. I love sex jokes even though I have cut back on them now that I have a little one. The people I love to share them with are ex’s who are friends.
They are ex’s for a REASON and they neither a. try to mack on me for real or b. let their significant other go nuts on me. Granted they were smart in letting these ladies meet me and letting me make friends with them before they made snap judgements on me.
You should talk to him more on why this makes you feel insecure in your relationship once more and see what he says. You may need a man without kids, because you can’t deal with what comes with a mixed family. No shame in admitting that and moving on.
Best of luck to you!
