Currently 28 weeks pregnant. So far questions and comments aren't too bad (if predictable) and I'm politely answering everything. This evening BIL asked me if I'm planning a vaginal birth or a c-section (phrased exactly like that). I decided to stand up for myself and tell him I didn't want to discuss that with him, but found it really odd that he asked.
For context he's absolutely devoted to SIL and clearly makes her happy which is great but he's very intense and difficult to spend too much time with, partly due to the way he approaches conversation. This evening he's asked me what I actually do at work, declared how much he misses SIL, talked about how focused he is and how he gets on with things (as a way of having a dig at ex BIL) and told the story of him and SIL getting closer before she split up with ex BIL (which we basically know) and emphasising how moral he is for trying to avoid seeing her when she was married and not actually doing anything, even though he really liked her. So much of his conversation generally is about their relationship and how perfect they are for each other, or is describing the sort of person he is, which I find really unusual. He's staying with us atm so left him and DH drinking wine and currently resting upstairs!
They're in the process of moving to same city as us and I'm not sure how to manage seeing him so much more often (although very happy about seeing more of SIL). I try to be polite and friendly, and in small doses he can be ok, but AIBU to find him hard work and look for ways to avoid spending too much time with him?
