I think it's not very nice - BUT, I have a question.

How long have you and your boyfriend been a couple? If it is not long, then perhaps that's why he's putting this trip ahead of your relationship.

When I met my BF, it was in the end of May. When it came time for Christmas that year, he and his son went to spend the holiday with his son's mother!

At that point, my BF felt that his son came first. And that meant, whatever was necessary to make that happen is what he chose to do.

I was hurt - and angry - and I felt threatened in our relationship, because I couldn't understand why he would do such a thing.

Do you know, it is now 10+ years later and I'm still with that same boyfriend?

Hon, I tell you all this to show you that there may be a perfectly legitimate reason for your boyfriend's behavior; at least, in his eyes.

If you think about it and decide to stick it out, then you're going to need to talk to him about it and see if the two of you can reach some sort of an understanding.

But if neither one of you is truly interested in exploring the other person's feelings with a means to understanding them, then it's probably best to do as Anna suggests and call it quits.

Best of luck to you both.
