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

My ex and I are having a baby together. Totally unplanned but we made a decision together to keep her. There's complications that require for me to have surgery this weekend and my ex feels obligated to come help me post operation. He has a trip planned this weekend that he's already paid for and when I told him it's not necessary for him to be here he got mad saying he would rather miss his trip than have me hold this over his head for the rest of his life.

We have a very complicated relationship. We're both "in love" with one another but we can't get along. I know he cares in his own way but I don't want him to sit at my bedside just to avoid some kind of punishment from me. How do explain this to him? Or do I just let him come be here for me?
<bot>: ex boyfriend wants to take care of me after an operation because he fears I will hold it over his head if he doesn't. Do I let him or tell him to go on his trip instead?
