Sorry this is going to be long winded, but I think it's important for all the details to be shared so you have the full picture.
I have been with my girlfriend (same sex couple) for 4 years, my girlfriends brother is getting married in August next year. My girlfriend is a bridesmaid in the wedding party so will be quite heavily involved in it all..
However I do not want to go and this caused a massive amount of tension/strain for the past couple of days since I bought up that I wouldn't be attending
The bride has been with the brother 6 years and whenever I have been around her and my GF's brother, I have been very amicable and I would say we are friendly with one another, i.e christmas gifts, coming over to our house for tea, spending time on days out occassionally, she's somone I see 2 x times a month, sometimes more - so we are not estranged.
There was a hen do for the bride, a few weeks back, my GF was invited along with my GF's other brothers girlfriend (of 1YR) and my MIL and mutual friends - I was excluded from this. The reasons being that because we are a same sex couple she didn't think it would be 'fair' for the other people there to have a couple in attendance when all the other women had left their boyfriends/husbands at home. My GF did challenge this only after I had made a comment about this and said that if I was a male, I'd of been invited to the stag do, so I wouldn't of been excluded entirely from the fun, where as everyone else got to go.
I'm obviously hurt and upset about being excluded and had to watch through social media all the fun everyone else was having..I have known SIL for 4 years, so I don't think its the amount of time me and GF have been together that's the issue. We are in a serious relationship and have bought a house together, I'm not a new date on the scene.
It all came to a head a few days ago, when I told her I didn't feel comfortable attending the wedding, I feel like a pity invite, I haven't been added to the group chat made about the wedding, nor have I recieved a physical invite just verbal confirmation from my girlfriend I'm invited. I just feel I'm not exactly wanted there, the hen/do has clearly shown her feelings towards me.
My GF is staying the night before the wedding, along with people that aren't in the bridal party (again I've been excluded from this) - so I've said I won't be going, and I'll be telling the bride/groom my reasons.
My girlfriend doesn't see my point and thinks I'm being difficult for the sake of it, and has been giving me the silent tratment for the last couple of days, and I feel anxious with the situation now and like I should just say yes, to appease her - despite me not wanting to go. Before the silent treatment began, she had been asking me quite a few times to please just go, I kept saying no and she just kept asking. I feel like I'm being manipulated.. I know she's upset because I won't be there however I feel like my reasons are valid and should be respected. I want her to go, and enjoy her time with her family at the wedding and celebrate, I just don't want to have to go with her...
So AIBU?
