i was approached by a friend of mine about going in as partners and providing security for an upcoming event in our town. we bid on the contract and won the bid. the agreement between us and the show was to get half the money upfront 1 week before the show then the rest the nite of the show. my "friend" went and picked up part of the money while i was out of town on buisness. he sent me a text instead of calling me and said he no longer wants to be partners and wants to do it by himself. he said it was his idea and he was jus gonna do it alone. the agreement between us was 50/50 on everything. is there anything legally i can do for this?
