I come from a seperated family myself. And my dad's side of the family has invited myself and my boyfriend on a family vacation. I have never been very close to them. They had origionally extended the invitation to his daughter as well. But it had become a major issue with other family memebers. My boyfriend's daiughter is 7. She has not had a good impression on my family. They see her as a pest more than an addition to the family. My boyfriend is aware of that and is very understanding. She has major behavioral issues that we've been working on together. We had discussed that it probably wasnt going to be the best idea for her to come along. He has 50/50 custody of her and the vacation lands on one of the weeks he has her. His parents were more than willing to watch her for the couple days that we are gone. I had suggested using his "one week of unintrupted vacation time" that was stated in his divorce degree to have her come with us on our own little family vacation on partial of the exes week to make up for the lost time during his week. I am not sure how well all of this is going to blow over with the ex or if his parents are really as willing to watch her for us as they say they are. My dads family has paid for everything for us and the trip is coming up in the next couple weeks, but I am starting to feel very guitly about taking a trip without her. The last time we had taken her to sea world and the san diego zoo were terrible. Tantrums every couple hours, contant complaining, not wanting to go see anything or do anything, hating all the amusment park rides, not wanting to explore anything anyone else wanted to do, and so on. So I do feel like her not going is what's going to be best, but again, I feel so incredibly guilty leaving her. My boyfriend was very much against the idea of leaving her, but after talking to his parents and planning a whole other trip with just us three, he agreed it would be the best solution as well. I don't know if my guilt is telling me we shouldn't go with my family or if I am just overthinking the whole situation. Would it be a different situation if it were not his kid week? Should we have just told everyone that she has to come with? Should we just not go?
