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.
Definitely don’t introduce a stranger to your child on a family trip just to make your ex jealous and/or take advantage of their new partner. This is a shitty thing to do. Just spend the free vacation with your kid or don’t go if you can’t be civil.
