Pregnancy & Birth Discussion

What to do?

i am currently living at home with my dad, brother, and grandparents. we live in a 3 bedroom house and i have realized there is no room for me to raise my baby in this house. we are simply too crowded. i am 9 wks prego and my boyfriend has been on my case wanting me to move in with him since we found out we were going to be parents 4 wks ago. he is 18 (im 16). he has a good job, his own house, 3 bedrooms, pays all his bills, and is trying really hard to prove to me that he is willing to have a family with me and this baby. his family believes that once a girl gets pregnant and the parents care and love each other then they should move in together since thats the right thing to do. My family dont believe that but they all did it anyway when they were younger. i really do want to live with my boyfriend and try this family thing. i just dont know how to tell my dad and grandparents i am wanting to move out at the beginning of june (wen school gets out) i know that they are gonna try to do everything in their pwr to stop me and alot of hard feelings are going to be caused. they do not understand that i am not a little kid anymore. i am about to have my own baby to raise and it would be really nice if i could do it the right way. i do not want my baby to be without a dad. the only reason my family lets me have anything to do with him is because they want him to help THEM out financially. i say if he is wanting to do the right thing and be a good parent and be here for me and our baby then why not give him a chance? you dont find many 18 yr old guys that actually want to stick around and do their part. i got lucky. so my question is how do i deal with my dad and grandparents in going about this moving out of their house and branching out on my own? they are really old fashioned and still treat me like i am five years old even though i have proved to them time after time that i am more grown than they are at times. i really need help. thanks in advance.
