Being stucked in e middle...

I've juz realize something..
That I've hurt someone pretty bad.. Bt the thing is he won't utter a word abt it..
He's e one whom I adores n loves most.. N he hasnt been talking to me for days..weeks..

Maybe I shouldnt hv promise her that I could b her bridesmaid.. Maybe I shouldnt hv..
Im kinda regretting abt it now..

Hell.. Its kinda hard to owaz be in the middle of something at times..
ezpecially if your in a special relationship with the both of them..
What should I do?? Aft watching a video that he posted.. It really speaks abt him..
N with that.. It really kills me inside.. where Im gonna be e girl's bridesmaid..

He pretends to be fine in front of me.. But i know that he's hurt in a way i did..
maybe I shouldn hv promise her.. maybe i shouldn hv plan everything.. maybe...
GAH!!! I really made a big mistake this time.. SHYTE!!!!

I feel like crying.. I wanna say Sorry to him.. I really hope that I'm in his arms hugging him.. saying that I'm sorry..

Sometimes its really hard for me to make decisions between two.. But I think this time.. I'll go with my guts n say that I couldnt be her bridesmaid.. But I'll help her with everything she needs.. other than being her bridesmaid/jie mei...

In e end.. today..I told her that I couldnt be her bridesmaid... She's sad cum angry.. sighs.. Its really hard to tell her.. I'm really sorry that i hv to make this decision..
Due to his current situation.. I hv to think abt him n his feelings..
feel like T.T-ing rite now...
what should i do to make everything better??? What can I do to make e situation to be like before??
