I don't want my brother and his wife in my wedding anymore

Almost two months to go and my brother and his wife have done nothing but make shitty comments and start drama. In the begining I just ignored them but it's getting harder. The most recent was them upset we're having a afternoon rehearsal which ended with my brother calling our mom to ask "what the hell is wrong with your daughter, doesn't she know rehearsals are suppose to be at dinner time?" Whatever then don't flipping come. Last night he called our mom complaining our wedding shower and bachelor/bachelorette parties are on June 30th. They wanted their sons bday party on that day. My mom told him these parties have been planned for months his response was "well AJ's birthday is June 20th EVERY year." So even they won't be coming to any of those parties and he'll "know" who "really" cares about their son by who shows up to the bday party. Besides the comment of who "really" cares about my nephew I'm totally p*ssed at the fact my SIL has said she'd help with these parties *continued*
