<human>: So I'm getting married next year. I had gotten all my groomsmen lined up, or so I thought. One of the guys I was going to ask has been my friend since I was in 10th grade. We've always talked about being in each others wedding etc. 

When my fiance' and I had finally set a date my buddy sent me a text saying he supported me getting married he just didn't agree with it. He doesn't get a warm fuzzy about my fiance'. He says there are things that rub him the wrong way he just can't put his finger on it. 

At first I was going to ask him to be a groomsman and just shuffle him at the end, away from my future bride. However that thought changed when my fiance' went on FB and found that my buddy and his g/f had both blocked her from FB and pinterest. Now she doesn't want him to have anything to do in the wedding party. I'm torn because of the friendship that he and I have had all these years. He is the only one that doesn't get a warm fuzzy about my fiance'. At first I chalked it up to you don't have to agree with who a person is dating but if you are friends you'll support them no matter what, now I don't know what to think. While I want him to be involved if he doesn't agree with my choices, what's the point, no matter what history we have? Easier to ask people on here rather than talk to someone in my life about it because I'm a man and we don't share feelings.

Any fellow redditors been in a situation like this before? What do you feel I should do?

Summarize the given text in a few sentences.
