(f18) and my boyfriend (m20) have been doing really well, and it's almost summer which means it'll be prime time for him to invite me to his family lake house. His mom welcomed me to spend the night there cause it's an hour and a half away from where we life. (Boyfriend and I don't live together, close but we still live with our parents) I went over there to visit a while back and road on the boat with my boyfriend. He drove the boat and it was fun, except his dad was there... and his dad makes me very uncomfortable. Every time he looks at me I feel like I'm being stared up and down, interrogated, etc. My boyfriend has noticed this too and told me he was glad I wore shorts under my skirt, when I asked why he said he saw his dad staring at my body and almost yelled at him. I'm afraid to be left alone around his dad cause I get a bad feeling from him. I've spent the night with my boyfriend before, at times where his sister and mother were home and his dad was not, but I just have a bit of fear that if I spend the night when he's there, he's gonna try to creep on me.

Am I making a big deal out of this or should I trust my gut and be cautious?
