Well it sucks and all, but maybe he just didnt believe in marriage with you. Everyone deserves to be happy, and if you truly love someone, you'll want them to be happy, even if its not with you. Try not to dwell on it, you were invited so he obviously still wants you in his life.

What a douchebag, I hope you punch him

Kick him in the shin when he is presenting the vows.

Look, I agree that it was kind of douchebaggy to send you an invite, but aren't people allowed to change their minds? It sounds to me like you still have feelings for him, in which case YDI for being so clingy and desperate. I wouldn't want to marry a girl like that either.

evidently you're still not over him...

you should go to the wedding and tell him he was right about marriage and you love being single and tell him about all the fun you are having in life and make him feel like shit for being such a hypocrite.

ouch, thats like a kick in the face, but at the same time, people change... you dont tell us how long its been since you broke it off, but evidently long enough for him to get on with his life and find someone he cares enough for to change his mind about things. or, he's an ass. either way, bummer on your end. :/

lol #16 has the right idea..but bottom line: He didn't believe in marriage...with you lol

haha at least he invited u

Yeah, FYL. People can change their mind and should...so sure, if he changed his mind and gets married, that in itself is cool. But it's still one HELL of a douchebag move to send a wedding invite to your ex who you broke up with because you didn't believe in marriage. "Hey, ex! Yeah, I know I told you that I didn't believe in marriage so we should break up, but I found the one! Isn't it great? We're getting married! Yeah, yeah, maybe we were serious enough that the M-word popped up more than once and we broke up, but haha, come celebrate my marriage!"
