Feeling expression with family help.

B

Well I'm almost 20 and I've always had huge anxiety when it comes to talking to my dad and telling him how I feel. I always let him run over me and I take it. I've never been able to stand up for myself and tell him how I really feel about how he's treating me. Recently some things have happened between him and my daughters dad and I'm not happy with how he treats him. I love my S/o we have a home together, a beautiful baby girl and it's not going to change any time soon just because he don't care for him. This man treats me right but my dad absolutely don't try to like him. I need advice on how to talk to my dad about how I feel about what's going on and how things need to be if he wants me and my baby around. I mean long story short he got a wreck in my truck, that's in my dads name and insurance. He's helping me take care of insurance until I'm out of college. My S/o has a full time job and is going to pay for what needs to be paid for period.
