<human>: Can you provide a brief overview of the text?

My boyfriend and I agreed to go on a trip with friends, but shortly thereafter I found out I was pregnant. For medical reasons I will not get into, abortion was advised by the doctor, and we 100% agreed. 

His friend, who arranged the trip (it was to celebrate his birthday), already booked and paid for us. When he brought up the details of the trip later, etc. (and this was the day after I found out I was pregnant) I said I might not be able to go after all, but didn't explain why. He was annoyed, but didn't probe, only saying we better go and not screw him over. The abortion wasn't arranged at this point. 

Anyhow, the abortion had to unfortunately be scheduled to coincide with the trip. And I wouldn't have gone anyways, given my circumstance. In the interim, the boyfriend's friend was telling him again that he better not screw him over and back out on the trip. 

My boyfriend said he wanted to be there for me to support me through the abortion, but said that he couldn't due to the commitment we made to his friend, and the money involved. He ended up going on the trip. 

What should he/we have done in this situation? I'm a little peeved that I had to go through the abortion alone, while he was having a blast with friends, but neither of us wanted to let our friends in on the very personal and medical reasons that I could not attend. We did commit in advance, but circumstances changed...
<bot>: Boyfriend went on trip with friends that was planned before I knew I would have to go through an abortion that coincided with trip. I'm peeved.
