My parents Vs. my Boyfriend

so i have been dating my boyfriend for about a year and a half i love having him around and i can honestly say i could see myself married to him in the future <3 i admit sometimes he can be a bit childish but then again so can I. my parents still see me as their little girl who wasn't ever interested in boys (cuz i used to be kinda ugly back in the day >_<) so when i invite my Bf to go places with me they are annoyed only because i focus so much attention on him Vs. them. back in the day we'd go to the city for plays and such and it was just the rents, bothers and myself and i tented to interact with my parents more cuz my brothers were too busy goofin off. now i focus more on my Bf. he is an ony child and his parents love to have me around! they take me out to dinner and stuff all the time. they invite me to events and everything. no fuss. no problem. why can't my parents be like that seriously i am freaking 19 years old (in 26 days) and they still are acting like children. they should know by now how i feel about my Bf and that he is now one of the focuses of my life. they need to stop being sofa king selfish and let me go just a little bit. i already go away to school so letting me go is not a big for them but this one thing keeps them mad. ugh i can not wait until i can be free completely free!!
