Dh mum hasn't contacted him or spoken to him directly except to say hello when he goes there ( rarely) for quite a while maybe a year or more? Friends of family had wedding and Mil went and got dh an 'outfit' to wear, he said he didn't want to wear it and she got offended. She also brought me a dress to wear and seemed offended when I turned up in something else!
Her dress didn't fit me.
They wanted us all to stay in the same hotel but we wanted to stay apart from them elsewhere and be independent. Fil asked dh to give his aunt a lift to the wedding venue but again dh didn't want too because other family members were all in the same hotel including sil who can drive, and they were 5 mins from venue we ended up about 3 miles away! We had our then 4 year old with us and I wanted to go to hair dresser in morning.
They massively sulked and fil interrogated me at wedding over our choices, Mil barely spoke to us! Fil gave dh a short speech on how upset Mil was he wouldn't wear her outfit!
Dh even did a speech at the wedding and Mil always pegs him as shy.. Neither sil nor Mil said a word to him about the speech.. To be fair fil did..
Since wedding Mil gone very frosty which has been quite nice actually but whilst relations have soured she still wants to see our dc... Dh drops then off occasionally but she barely speaks to him!
I just feel if she really cared for her son she would have stopped sulking over the the outfit and hotel and accepted that a married man will make his own choices and congratulated him over the speech? Sil also? Sil barely spoke to her dB and sat glued to Mil.
I don't feel comfortable going there anymore, the last time we did Mil served us tea and cake which was v nice but then went off to different rooms with a the dc leaving us at the table with fil whom I can't help feel was givens the job of keeping us there chatting so Mil could go off on her own. 
That year for Xmas Mil gave us socks each which were lovely but previously had given us more. We went for Xmas and Mil and sil and sil bf all sat on the the other side of the room in a sort of huddle, with our dc (no other dc in family) and again dh and I are sort of left with fil
when dh or I moved to the huddle they seemed to move away.
Fil can only chat about certain subjects, he's OK but it wasn't by vision of Xmas being interrogated and chatting about trains, dry rot and investments 
At one point dh did something to his hair and I said out loud.. Dh you look amazing or something like that, and Mil quickly interjected... It's because he's my son.
that's the closest thing to a compliment I have ever heard her say to him!
This is bizzare behaviour isn't it?!
