Relationship advice?

No, you are absolutely not overreacting. I think you should end this relationship, it is unhealthy. if you continue in this relationship you are going to get hurt, trust me, I understand. It may be hard to let go, but once you do, you will eventually find the one you are meant to be with. A guy who really loves you and cares. I do hope you take my advice, because i do not want you hurt in the end. A guy who does the things you've said above is not worth it, and you deserve better. I hope things work out for you.
