Dad dislikes BF

My dad really doesn't like my BF. We broke up for 2 weeks but then we were able to work things out but my dad still holds it against him. Additionally my mom told my dad we were having sex (like wtf) and he's not too happy about that either. I'm in college and I feel like my dad is trying to control my life. It's so frustrating and upsetting and I don't know how to at least get my dad to respect my decisions.
