Ask the OT - how would you handle this - wedding drama

A wedding is coming up. The GF's bro is getting married out in CA.

A little background. GF has two kids from a previous relationship. Baby daddy is a degenerate drug dealer (who has spent time in prison for such). I really don't care for the eldest child - she ran away last year and that resulted in a long and expensive custody battle with lots of drama. This kid is a mean little shite and has a mouth that makes you want to wash it out with soap (not my kid - so can't do anything but try to avoid interacting with the kid).

GF wants to turn this into a big family vacation. I told her I'd go out for the wedding and fly back. I don't want to spend a lot of money on this trip. I've been to CA many many times and done everything and seen everything I want to see there (it's already expensive as hell just for a few days) and work is extremely busy so I can't take much time off work.

Well, GF is po'd at me because I'm not going to stay out there for week with her and her daughters. I told her that if she wanted a family vacation that she and her daughters should stay and have their fun. I'd go for the wedding and stay a few days and that was it.

I really don't want my gf looking at me like I'm supposed to be buying meals and entrance fees to Disney and Universal and shite like that - that doesn't sound like a fun time to me at all and I'm pretty sure it would just piss me the frick off.

I dated one other woman with kids from another relationship and we took a vacation with her kids and it was pretty much zero fun and all expense for me. It was also the end of our relationship.

anyway - end dear Facebook.
