My dad is confusing me

My boyfriend use to like my dad up until recently. My dad started being a jerk. I love my boyfriend and my dad very much.

My boyfriend and I are wanting to get married in July, but my dad keeps changing his mind on whether or not he wants to sign the papers for us to get married. My boyfriend is mad at my dad because my dad is making me unhappy, because he is to busy trying to make himself happy, and I live in a state to where you can't get married until your 21 without parental concent.
I might be pregnant but my dad doesn't know yet. My dad and I are always arguing because him and I are too headstang. I'm very happy with the guy I'm with and my dad said he wants to see me happy, but he also doesn't want to give me up. My dad keeps saying that I'm not in love with this guy when I know I am. My dad is making it to where me and my boyfriend are arguing all the time. He is stressing my boyfriend and I out about everything.

My boyfriend wants me to move in with him, so he can support me and his unborn child if I'm pregnant. My dad has already told me that he wasn't gonna stop me from leaving, but he told me that if I left that I couldn't come back. That he wasn't gonna be my dad anymore. He is always telling me to get out. He is really confusing me.

What can I do? My dad is upsetting me and he always finds a way to make me feel like I'm not a good daughter. I've tried talking to him but he wont listen to me. Please any advice would help. thank you for your time.

Hmmm....I had a head strong dad to. I will never forget how mad he was when I told him I was moving out. He was not good at expressing himself and he did not see it coming, so I think the anxiety of everything hit him at once. Dads are not always good at expressing their feelings, the mushy ones anyway lol Find out if your pregnant, if you want to move in with your bf do it, dont let anyone guilt you into doing something you dont want to do. You are 18 and though he might not want to let go, inevitably he will have to. Just make sure you are making the right choice for you. You can be mad about the attitude but dont be mad about him loving you and wanting the best for you. I hope it all works out in the end.

My dad is exactly the same but when i moved out with him and started planning the wedding, he came around a bit
Go ahead and do what you need to do, if he loves you he'll love you either way. He's your dad

Thanks for your advice everyone. It has helped me some what deal with the situation I'm in. once again thank you and I'll keep you posted.
