too bad :( but at least they aren't rude or something...

Honestly if my family hated the man I wanted to marry, I'd prefer they keep it to themselves than be outright assholes to a point that would make it difficult for me and my spouse to partake in family gatherings. And at least they're not giving you a dilemma like, "if you marry him the two of you are not welcome in my house". Things like that can put a strain on marriages, and who knows, maybe they will eventually grow to like him.

Well if they pretended to like him it's not as bad as them not allowing you to be with him.

Elope and tell them why.

I don't see what's wrong here their supporting you they just don't like him that sucks but nothing to be to upset about

They are just trying to be supportive of you. I'd have them sit down and actually discuss what they like/dislike about your fiancé. Maybe they know something you don't? Regardless, if you're marrying him you're the one that's going to be living with him, not them. Then again, no one in my family liked my sister's ex husband and she married him only to find out he'd been cheating on her.

I'd like to know if they have valid reasons for not liking him.

This counts as one of those things better left unsaid. Which is probably why they didn't feel the need to inform you of it. Look at it this way... They cared enough about your own feelings for him to not fill your head with their own dislikes. It's apparent they know it's your life and your choice so why be upset that they've respected your choice and feelings enough to be respectful and nice to someone they don't like??

That sucks but no ones opinion matters but yours. Your the one marrying him, not them. It's always nice to have the support of your family but I wouldn't worry about. You should be happy though that they are civil. When my mom got married, my dads mother told her that it must be so nice to have a father for her child because my mom was a single mom. His family was openly awful to my mother. It could be worse.

Spite them back by having a good life with the guy you love. If he's really the one, who cares what anyone else thinks? And maybe seeing how happy you are in your new life will soften them up. If not, distract 'em with grandkids
