DP and I have been together for three years and we’re very happy together day-to-day. We both have young children from our previous relationships who we share care of with our respective exes. We don’t live together and we’re both happy with that.
His relationship with his ex-W is good: they cooperate well with their kids, they are respectful towards each other, they are friendly. I’ve always seen that as a good thing… But now they’ve gone on holiday together, they will share a twin room, and I just feel horrible. I raised this with him and he reassured me that there’s no attraction, it’s for the kids, I must trust him. But I feel uneasy and tearful.
