Thank you all for the replies. I often catch myself acting way too needy mentally. I try to shut it down and not show this towards my partner, as it's a big turn off.

This is sort of my dilemma: Do I bring up how I'm not feeling appreciated/admired? Or do I simply try to love myself and exude happiness/indifference?

The latter makes sense to me, because if I start questioning things and prodding, that will make me look weak and needy, right? It's just SO hard not to say something like "hey, am I wasting my time with you? I've been getting the impression that you could really care less about being with me 90% of the time."

...Not that she's hostile towards me, it's just SO much different than it was in the beginning. And she's got emotional issues, I get it... it's just hard not to think I'm the cause of them. I just kind of crave affection in a relationship, and when it's not happening, I freak.

I feel like I'm ranting - I apologize. I just feel a little lost and don't want to say the wrong thing to push her away.
