Is it normal my boyfriend's dad freaks me out
So I have been with my bf for a little while now. We lived with his dad for awhile (paying rent also) but eventually ended up moving out because I'm not comfortable around him at all. He's very moody it seems and sometimes is fairly nice to me but other times, he couldn't be more indifferent about me as a person and we just don't have a relationship really. Sometimes he has a very harsh temper and one time it caused me to leave him a horrible note because one time he told my bf that he felt awkward around me and felt like a stranger was in his house and I heard him talking about me and sounding very angry. Instead of confronting him and talking to him about it, I left him a note (I was angry) and stating that I would move out if he wanted. This was the wrong thing to do I know but I can't change it now. He has done other things that caused me to want to avoid him such as eating my food whenever he pleased/using my laundry soap without asking and coming into our space downstairs often without asking/turning off led Christmas lights EVERYTIME i left the house/ having very loud sex with his gf when I am there alone. (Creeped me out and I left) I just don't understand him. He seems very cold. Last time I saw him. I didn't say hi right away and when he actually did say hi to me, it was very irritated-like like I should have been the one to say it. I don't know how I can fix this or if I can. Advice please? I love my bf. I can't understand his father. I avoid him and it shouldn't be this way.
