Bf and I have been together for about 8 years now. We have 2 children under 3.
He expressed he wants us to get married but his mother is absolutely awful and we don't speak (haven't for about 2 years now)
She was fine until I'd had my firstborn (daughter) then got baby rabies and got super possessive acting like she was the parent. I let a lot of her behaviour slide but when we were about 6 months along with baby number 2 (son) we sat down and had a face to face chat with her around boundaries because I didn't want the same experience again. She had her friend there for moral support.
We were both respectful with her but she pitched a fit and now insists on seeing my bf and kids without me. This causes issues in itself.
There has been a lot happened since that has opened my eyes to how manipulative and nasty this woman really is.
Bf wants us to get married but I know if I do then I am legally tied in and, if his mothers behaviour escalates again to the point where I can't cope with it, it will make it harder for me to walk away. I'm already worried about what she says in front of my children when I'm not there.
On top of that, if we did get married; I expect he would still want to invite her and I would have to tolerate her for the day. I can't stand this woman, it would completely ruin my wedding day to have to be anywhere near her.
We do really love each other and he would love for us to be an 'official' family so I feel bad hurting his feelings saying no. He's an amazing dad and boyfriend and he does a good job of protecting me from his mother.
