It does sound like you are too attached. I can get to that point too. You know what I have realized? If I give my husband space, time with friends when desired, time alone when needed, etc., first of all, he chooses to be around me more and, second, our time together is more fun and meaningful and we have more to talk about. I think that, to most people, when someone is naggy, whiny, and overly dependent (friends or otherwise), it is a major turn-off (I'm not saying you are being those things, but I sure can be when I'm feeling insecure!)

I've recently gotten back my old security and independence (slow but sure) and I have noticed a total difference in my relationship and how I'm treated by my husband- he is much more loving and affectionate and enjoys spending more time with me- not because he feels like he HAS to be or that I will fall apart if he's not around.

Good luck!
