That does seem a little soon, although you have to be flattered that he wants to introduce you to them. But yes, I'm with you: keep the horse in front of the cart. You are kind to be concerned with his feelings.
How big a deal is he making of you meeting them? Is it a special dinner for the purpose of meeting them, or does he just want to take you along on a casual family outing? Those are two very different things, although it doesn't really matter: if you're not ready, then you're not ready.
Unfortunately, there's probably no way to tell him without hurting his feelings at least a little bit, because he will likely see it as a sign that you don't like him as much as he likes you. Guys can be sensitive about things like introducing you to their families: they think it's a great honor, and your reluctance feels like a slap in the face. He might also take it to mean that you see no future in the relationship, even though that doesn't sound like the case here.
I would just assure him that you like him and really enjoy the time you guys have together, but that you want to take it slowly and get to know each other better before bringing family into it. It doesn't mean you see no future with him, and it doesn't mean that you won't want to meet his folks later on. But for now, you want to keep things simple and not mess up what you have by rushing things.
I bet he'll be able to handle that.
Yeah, I think I'd want to know how big of a deal this is to him, and how formal or casual this is expected to be. Keep in mind just because you meet his family, it doesn't mean you are promising to marry him or even necessarily making a commitment to a future of dating him.
I do think you should consider it a compliment that he wants you to meet them, though. So if you are going to put the kibosh on it, do it with as much kindness as you can muster, especially if you want to keep seeing him.
I don't think why not. It is a nice thing of him that means he is serious about you.
How do I tell my husband I don't want to meet his family... I mean, ever again?
You know, I never really understood what the big deal about meeting someone's parents is. All throughout life you meet others' parents; in highschool when you went over to friends' houses, at extra curricular events, awkwardly in line at grocery stores... Quite frankly, they're just people. People who miraculously produced an great guy, who you happen to be dating. So they can't be all bad, right?
Your boyfriend clearly cares about you. In my mind that means his parents are probably feeling a little bit of pressure to "get along" too. Not to mention probably have a degree of nervousness about meeting you (especially if you'd be going to visit them at their house, it takes a while to get comfortable in that situation). With that, I figure they won't be out to make things difficult or painful during your visit. I mean, yea they Are still people. And some people are total dicks. But I highly doubt your boyfriend would want to introduce you were they total dicks, especially so soon in a relationship when you aren't necessarily in it for the long run, death or in-laws do you part.
It's only a few hours of your life and then, ta da! The hard, mildly uncomfortable part is over and you can both move on to other things.
