How long should you be "talking?"

[WVU alpha phi]

Well I have a little update on the whole situation. He came over last night and I was talking about how my parents are coming to see me this weekend. He was like, "so am I good enough to meet your parents?" and I was like "Um I don't know, do you want to?" and he just kinda laughed and was like, "I don't know, then they might love me." I don't think I want to introduce him to my parents because I don't know how I would- like "Hey Mom, this is John, the guy I'm hanging out and hooking up with!" and I don't want her to get all involved in it like she usually tries to. Then later on in the night he brought up the relationship talk again and kinda said like "well do you just wanna be my girlfriend?" and I said "No, not if you're going to ask like that, just forget it, you told me where you stand" and then he acted like I had been all hurtful and rejected him. I only said that because he seemed like he asked in a joking matter AND he had been drinking earlier and even thoguh I don't think he was drunk, I don't want things to be like that.

Everyone's posts are really making me consider just breaking this off if he doesn't want me as a girlfriend. Are ultimatums (sp?) a bad thing?
