My brothers girlfriend has refused to speak to our Mum for nearly two years....

Why are they not talking? Sounds serious.
Either way it's your wedding, do what you want. You a close family or not? Resolve upset or just don't invite her.

I wouldn't invite my brothers girlfriend doesn't speak to any off us my brother doesn't even take his son who is one in October to his dad as won't let him so I am not inviting any off them I want my Mum and stepdad to have a great day not worry about that cow... your wedding do as you please

I would invite her at the end of the day you have been the bigger person and invited her she probably won't come anyway but she can never hold it against you xx

Cant your brother have a word with her? See if bridges can be built .
Invite her if you get on with her she can sit with your brother. Then she won't fall out with you. Up to her if she attends.

I agree with Terri Hudson- My fiancé's sister don't talk to him or me she said that her brother is dead to her even though he's done nothing wrong. We still invited her to our children's christening she didn't come and we'll still invite her to our wedding granted she still won't come but least we look like the bigger people. But it's your choice at the end of the day.

I would invite her and then it's her worry one less for you x

Invite her, if she doesn't turn up to most things she won't to this but as your brother clearly loves this woman you need to be the bigger person for his sake exactly as your mum is being by not cutting her out and leaving it to her to act like a child if she chooses

Hi I would speak to your Mum see what she thinks it sounds like your brothers girlfriend hold a gridge :)

Invite her,life is to short! Your brother is the important one

I would send her the invite anyway, it's her choice whether she turns up or not. I think not sending an invite would just cause more problems x

Sounds like it is not your Mum holding the grudge but this girl. I would invite her anyway and if she doesn't come then it shows her up, not your Mum. If you don't invite her you come down to her level.

You invite her then she has to make a choice .....
she refuses to come
She comes but doesn't speak to your mum
She comes,decides to grow up

Unless she does anything but the last ,she is the one who looks foolish and juvenile

If you don't invite her ,have no doubt that she will use it against you to cause more trouble

Wouldnt bother inviting her sounds type of bird thatl ruin ur day.

I would invite her. If she doesn't turn up that's upto her but sounds like she is the one with the issue you not you and your mum. If you don't invite her she may say she knew you didn't like her etc xx

I wouldnt be inviting her x
