The subject text is probably rubbish, couldn't think of how to word it. To summarise:
My DP and I each have children from our previous marriages. She has 1, I have 3. Something came up a few weeks back where I will have mine some of the half term, but she isn't having her son then (ideally we coincide, but occasionally stuff happens). When she heard this she said "it's okay I'll work away, I can't be here when only your kids are here I'll feel guilty and my DS will feel left out".
So I'll probably go away with my kids to see family then. Anyhow, today she's had some things through with work which means she's rearranged some of her DS time at the weekends which will mean he is here when mine aren't (we have them the same weekends usually).
Now here's the thing, I really don't mind having DSS around on his own, it's fine. But now I'm stressing, should I actually be saying that I'll go stay somewhere else (like she would say given the opposite)? Am i too laid back? Am i a mug? Am I not thinking of my DC feelings (will they get jealous?)? What do others do in this difference of opinion thing?
