I agreed to spend Christmas with a friend a few weeks ago, but since then Ive had another friend suggest something and Id rather take them up on that. But I dont know how to tell the friend who asked first. So as not to drip feed, I do feel taken advantage of by her quite often, she always manages to find a way for me to pay more than her when we go out, and Im sure Christmas will be no different. I know I should have said no at the time, but I was on the spot an didnt think fast enough. I dont want to fall out as we are in a shared social group and it would cause issues. ButI dont think it will go down well. Its still months away so I also dont think I am being unreasonable, but I do need to deal with asap. Any suggestions on how to handle would be appreciated!
