Breakup?

I just broke up with my boyfriend. I don’t know how I feel. He’s been stealing money from our savings, I only found out cause I counted the money, about 400$ is missing. He’s been smoking weed again, and lying about it. He’s been lying about his whereabouts. He’s been ignoring me. Was I wrong? He’s making me feel so guilty. He was doing soo good and now I feel his regression. I hate that I had to do this cause we’ve shared so much. Family trips, tons of nights of sleeping together... I don’t know. I’m starting college in the Fall and he is supposed to too. He hasnt made any effort. Help me please. I feel like I just lost the love of my life.
