Well I can offically say I am in the same boat as you. It's all Jay's family and none of mine are coming. My father has been long gone out of the picture since I was 10. My mother well we just don't see eye to eye on ANYTHING and my brother and sister.. well since they are on my mothers side of things and how I go about my life and where I lead myself.. (BLACK SHEEP is the best term to call me) they have nothing to do with my wedding. I sent them all letters letting them know about the engagement and got nothing back at all not even a call... sooo I am going and doing this alone... It will be fine in the end. I know who the people are that love Jay and I, I guess that is what matters.
I think this is why we did the DW in the first place.. Jay popped the DW on me, after starting to plan a local and well he was right... the "normal" stuff was already upsetting me. Sooo Jay's dad is walking me down the isle and then will be his B.M.
It's sucks when people don't follow through but I'm not going to let them bring me down.
