DH, DS and I went for dinner at SIL's house on Sat evening and had dinner with her and her boyfriend. I wasn't especially keen in going, but thought better to get it out of the way, and I think DH felt the same as he's not a huge fan of the boyfriend. We are 28 this year and SIL is 26, her boyfriend is 35. They have been together 3 years and aren't in any rush for marriage/kids etc. although his mum is dropping heavy hints about both to them.
The next day (Mothers Day), SIL texted DH at lunchtime to ask if she could visit our DS....Is this a bit strange? The reason we went for dinner was specifically so she could see our DS ( she lives 30 minutes drive away), and she knew it was my first mothers day as she had asked what DS had 'bought' me at dinner the night before?
SIL and DH don't have a mum, so she would have been going to her boyfriends mum for lunch/dinner I imagine.
The only reasonable explanation I can think of is that she didn't fancy lunch/dinner with her boyfriends mum although they get on fine? I feel like she is trying to muscle in on my day....I think it would be pretty normal for myself, DH and DS to spend the day just the 3 of us? My first reaction to DH in the middle of the restaurant was 'is she taking the piss?!*?'
Generally we see SIL at family meals with the FIL, other SIL and BIL about once a month.
