This happened a couple of years ago, but its been something that has really bothered me recently. Triggered by various other things that have happened
I was away (visiting my parents) with DC and Dh joined us for the last week of the holiday. BIL (DH brother) and SIL were visiting in-laws (staying with them) until DH left to join us. After this BIL and SIL moved into out house for the rest of the week as it was 'nicer' to stay at our house then with in-laws. They spent the week, even hosted a party!
I wasn't asked. Its massively upsetting me now as BIL has form for disrespecting my boundaries and this is a classic example.
DH thinks its absolutely ok for his brother to stay at ours while we were away, whereas it has upset me.
We can't seem to agree to disagree when it comes to this and it is causing massive tension between DH and myself. I know it was a while ago but it seems to have set the tone for our relationship.
Theres lots of other issues in the same vein but this particular issue has become a huge bone of contention
