She is nice to me when I see her, and as far as I know she doesn't have any sort of problem with me. I know she isn't forced to be friends with me, I just feel a little disappointed.
From what I've seen she was very good friends with his ex and they all spent time together as a group, but those two were also close friends and went for coffees and stuff together.
I've tried to suggest that the 4 of us go out (with her fiancé too) to my fiancé but nothing ever materialises. We attended a meal for her birthday earlier in the year and I got her a gift and card, recently it was my birthday and she didn't acknowledge it at all by even saying happy birthday or anything.
I graduated and his parents said congratulations on social media, she said nothing.
My partner claims she can be a bit 'stroppy' sometimes and has her own issues going on, I'll try to not take it personally. I feel a bit disappointed but there's nothing I can do, I can't force things. Has anyone else had this?
