Hi Write
I haven't seen your other post, but I appreciate that you feel hurt by his comment as would anyone. Were there any other comments or is this the only one? Also how long ago was this? If this was a while ago and there were no other comments then I feel this may be something to let go... maybe ask yourself "is it worth the upset with your friend?", however if he speaks down to you each time you see him, then that would be a different matter. Also, do you have any mutual friends, what do they think about him?
As someone who recently got married this touches a nerve with me as I feel a wedding is where friends and family should put aside their differences for one day and be there for their friends/family. It is only one day after all.... even if it's an early wedding, it's only 12 hours of your life. I have done this in the past for my friends and I would again. Also, even if he spoke down to you on his wedding day, you could just turn round and say I'm here for the bride. I feel that because your friend keeps asking you, it's because she wants you to share in one of the happiest days of her life. This itself speaks volumes to me and to me anyway, shows that she values you.
I will tell you this though.... with our wedding, a good friend of mine was moving to America about 2 months before our wedding and she wouldn't be able to make it. Her boyfriend had moved across earlier and a month before she was due to go, he broke up with her. To say she was gutted is an understatement and I went round with tissues, chocs and flowers for her. I felt for her so so much, however she was also a friend who helped me alot, sticking bows on, helping organise taxi's etc and she had a fab day at our wedding. She told me several times how much she enjoyed it, even though she didn't know a great deal of people there. Can you imagine what it must have been like for her, feeling so down and then so enthusiasic about your friends wedding? My point is that although it was our wedding, I appreciate her so much for giving her time and being there.
My two cents anyway... for what they're worth.
Take care
