My boyfriend has been lying to me and trying to avoid me?

After a major fight we were suppose to go out last night to this annual big event right. So he sent me a text to say that its been cancelled, but i knew he was lying, coz my brother went there and it was not cancelled. He must think im so gullable. Should I confront him and send him a text which he probably wont reply to. He's been avoiding me for more than two weeks now and we had a big figth on Sat that left me in tears and him laughing about it and calling me demeaning names. Whats a good, witty, intelligent text to send him. what should i do? help meeeee! Please guys
