I admire you for having so much insight and self-assurance at such a young age. I’m 31 and I don’t think I would be able to have such a mature assessment of a relationship! I agree with what everyone else has said – right now is time to let go. If he hasn’t stopped the destructive behaviors despite your vocal objections, it’s unlikely he will be able to stop. Or if he does stop for you, he may begin to resent you. People grow apart, especially through big moves and life changes.

By staying attached to him and hoping he will change, you are closing yourself off to other relationships and opportunities that may fit your values and goals better. Especially at 18, it’s important to explore and find something that’s truly a good fit.
