LOL! For me we cross that point when we have decided that we are only seeing each other, when we talk about marriage, and what each other wants or need from that marriage, when we have discussed religious beliefs, and when enough time has passed that we have put most of our cards on the table. To me there are 3 levels, 1)the getting to know each other level, 2) when we decide that we are in a relationship and we are exclusive, 3)when we get to a point where we start discussing marriage and what we both need to get to that point. No, I have never introduced my parents to any of my boyfriends, to me it never reached point 3, so my parents didn't need to meet him. Before I let someone into my life that far, I need to feel as if there is a good chance that you will stick around, and that I want you there. I have definitely talked to my parents about them (I have 3, my mom, my dad, and dad the sequel), and discussed problems, they know of him, but they never met him. When I bring a man home, my parents will definitely know that I am serious.
