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.
Would your ex go if the situation was reversed? Would she be willing to “put all the bad blood behind”? Not if she had any self respect. Frankly, I think just asking you is an insult in itself. It puts the onus on you to be the “bad guy”.
Your feelings are completely valid. Your son is old enough to understand the basics. DO NOT GO. She’ll ask, but don’t bother explaining why. She lost her right to know your heart when she betrayed you.
