<human>: Condense the text into a few key points

I am having a procedure done to help keep me from miscarrying our baby. My SO works 8 hours away and planned to go on vacation with his buddies. The surgery puts me at high risk for strokes/bleeding out and we've actually discussed what my wishes were in the event something were to happen to me. He offered to come to help out and I said I could probably manage. I assumed he knew he should come--considering this is his child--and that even though I said I could "manage" that he would still be willing to go.

So then he goes and books the flight with his friends.

I was really trying to just be nice and tell him he didn't have to "babysit" me but I thought he would WANT to be there for moral support?? So now this turned into a huge fight and I don't know what to do. Too mad to believe he can even think of enjoying himself while I'm literally putting my life at risk to save his child.

Any advice??
<bot>: SO chose to go on vacation with friends rather than be at my side during surgery to save our child just because I mentioned that I could "manage" without him here.
