Ok... so last night I went out to my cousin's birthday party. I went alone because she said she had a headache (period was on), so I told her just rest at home. Well, during this party, I just accidentally met and had normal conversation with this cute little latina chick. She got all into me....and I was a little drunk.... well, next thing I know, in my drunken state, we are in a bedroom in my cousin's house and we're in the middle of some "activities".....this girl was kinky and wanted anal....I was drunk, I don't know what came over me but I did it....well... we were in the middle of this as my significant other catches me... she actually got dressed and came to the party to be with me and apparently someone told her where I went. It was not my cousin, though.
Anyway, I don't know what to do. She is very upset at me, and I understand I messed up. It must be a graphic mental image burned into her brain....
I don't know what I can do to make her forgive me, I really messed up this time. She means everything to me and I want to fix this.
can anyone help? advice welcome, please.
