<human>: Give me a shortened version of the text

So here's the story...

Me and my ex were together previously for 3 years. 3 months after I popped the question, she broke up with me and stated that she was not ready for marriage. It turns out, she started dating someone that she was working with a month after we broke up. 

Fast forward to 6 months later, we reconnect and we decide to give things another shot. She mentioned to me that she wants to spend some days with her exes kid and that she really missed the kid and wants him back in her life. She said it has nothing to do with the guy, she wouldn't even be seeing the ex. I told her to decide between the kid or myself, and that I don't want any part of her ex coming in between us. We haven't talked for a week.

Am I in the wrong for breaking up because of this?
<bot>: Ex-Fiancee and I hooked back up, turns out she wants to still see her exes kid. I'm not cool with that. Am I crazy?
