I left home for University then afterwards stayed in the area near the University. My ex was a student there too and we stayed there after our marriage, so both sets of parents were some distance away. My MiL tried to talk him out of going out with me as I was a few years older than him and had a weight problem. She said "Why don't you find someone younger and slimmer?" I suspect she may not know that he told me! The first present she ever gave me was a weightwatchers recipe book!
Despite this rocky start I tried to put up with her interfering and had to be quite firm when she wanted to influence the children's upbringing.
I'm divorced now but still stay in touch with her. I feel sorry for her as she is in her 90s, nearly blind and quite lonely. My ex lives much further away than when we were together, so sees her less than she'd like and her other son lives abroad so she rarely sees him at all. When I gave birth to her first grandchild she started to refer to me as 'her loverly DiL' and it was clear her problem with me had been that she thought I might not give her grandchildren. They started asking when we planned to start a family as soon as we returned from honeymoon!
She never got on with her other son's wife and they are now separated, living in different countries, with one child living with each, neither of whom see their grandma! She doesn't get on with my ex's new partner either so if my ex visits it is always alone so never for long!
Although I feel sorry for her I know she has brought it on herself with her controlling attitudes and a tendency to think that no-one is good enough for her boys. It's very sad. My grown up kids visit her when they can but they live at the other end of the country so it isn't as often as she would like.
My own mum rarely interfered and one of my biggest regrets is not spending more time with her when the children were young as they didn't build a strong relationship with her as they did with my in-laws who lived near enough to visit regularly while my mum didn't drive and lived at the other end of the country. My ex wasn't keen to visit her very often either so she lost out. I saw her more after we split up but by then my kids were older and becoming independent.
When my son got married I told mmy DiL that I had hopefully learnt how not to be a MiL from my experience and I hoped she would benefit. Thankfully I totally approve of my DiL and I wouldn't dream of interfering with how she brings up my grandchildren!
