To keep it short: my ex-wife cheated on me with this guy, we divorced, she married him immediately after. Since January we’ve been co-parenting, she has our son (14 years old) for 2 weeks & I have him for 2 weeks. Her now husband is wealthy, and for the winter holidays they plan on going to the Maldives for 3 weeks (I agreed to give up 1 week of my 2 weeks; gonna get +1 week with son after the vacation). Apparently son has been asking his mom and stepdad if I can come as well. So ex-wife calls me and asks me if I’d like to go, all expenses paid by them, just to be with our son and have some fun - and let’s “put all the bad blood behind”. I told her I’ll think about it, but honestly I don’t think I’d feel comfortable. At the same time going would make son extremely happy obviously. Idk.
If I were in your shoes I’d sit down with the son and ask what he’d like, and try and explain why I’m uncomfortable being around his mother and her new fling. Then in the conversation figure out if his desire is greater than my hesitations, come to an understanding on what we feel the vacation would look like.
Would it be all 4 just… Hanging out? Then probably not. That’s the most awkward. Or would it be that there are things to do (planned) that could pair off and have some time with son, while his mother and fling does whatever they do? As long as those times are more frequent, and son likes the idea, sure I’d probably accept.
