His dad

Ive been with this guy for a few months and I just recently met his mom, she apparently loves me he says. But I just met his dad the other day and well to be honest I feel like I doesn't like or or trust me. When his dad and him were driving me home his dad was like watching me in the mirror and I didn't know what to do. I haven't got to ask my BF yet, but I don't really understand what I did wrong if he doesn't like me. I was my self 100%. And from what my bf said we actually have a goof bit in common.

Ladies, what should I do? I've never had this happen before.......
