need to vent

I Recently told my parents I'm pregnant and I plan to move out my boyfriend can easily support Me and this baby and he wants to. Well my parents are being so complicated and now are treating me like I'm 12. I'm an adult and being told I can't even see my boyfriend?!? I'm beyond frustrated that they're treating me like this. I wasn't asking for permission to leave and my boyfriend wasn't asking their permission to take care of me but my da did acting that way and I'm beyond pissed. I want to just leave but I know leaving will make it worse if I don't tell them I'm leaving, but I feel like if I tell them I'm leaving they're going to make sure I don't. I don't know what to do and I do not want to stay here stressed out and possibly risk harming my baby.
