Parents and boyfriend

Phoebe
I've been dating my Boyfriend for a while and we're really serious. I'm however nervous because sooner or later I'll have to tell my parents about him....my parents on the other hands wants me to marry someone from church. Plus I'm black and my boyfriend is white. I'm scared they may not accept him. The last time I tried to tell them about a guy I was dating it didn't go so well and I ended up breaking up with him. Any advice? I'm just so worried cause I love my boyfriend very much and don't want to loose him. He keeps telling me not to worry though. Any advice from you?
