T one thing at a time: you need to finish all this school work. Then you need to find an attorney that you like and believe understands your goals (but first you have to know them yourself).
Courts don't care about the minutiae. Keep a journal as suggested but don't try to strategically text. He's either being a dad, or he isn't. He's either helping or he isn't.
Take some time, figure out what you want deep down inside. At the first sign he's messing with the money, take action. Right now no one can help you because don't know what you want. That will become clear.
