Meet my Family

My boyfriend is coming to visit me this weekend and he is going to meet my immediate family.
He met my mother briefly once and he's met the cool cousins and aunt but now he is going to meet the people that I dread him having to meet. My family are generally socially normal but in the past whenever I've brought I guy home I regret having done so. It generally always kills the relationship.

As a teen and young adult I tried to give instructions like don't ring the doorbell, stay in the car while I run in and get this, but every so often a brave one decides to enter the lair. I think people working on the assumption that most people are alike can't comprehend how different my family might actually be.

I haven't told the family he's my boyfriend as this is something I don't feel comfortable discussing with them.
Every guy but one that I introduced to my sister has said "I don't think she likes me." The worse part is not so much how they treat the person, if you don't mind being ignored and looked at funny, the worse part is the critique that follows.

The hell I feel I have to go through with my family just to be in a relationship makes me want to leave town and never have to introduce anyone to them.

My goal is to let him meet my mother and be done with it. But he wants to meet everyone. I've warned him although I don't he fully comprehends my concerns and fears. I guess I'll have to be strong and tell them to stop hating.

I've discussed my concerns with my mother and she said, "why would you think they would treat him mean?" I went through the history of my dating and she just laughed. Even she had to admit that her children can be difficult.

His family has been great to me, I'm hoping that mine will return the favor or at least be neutral. *sighing*
