Undesirable...

What can I say, I still don't feel secure at all in this relationship, but why would I? Much hasnt changed to me. Dont get me wrong, There is an effort to be nicer on both of our parts but thats about it. Sometimes I feel so undesirable...like I'm not up to HIS standards....you know I really havent met ANYBODY outside of his family....ever...and we've been talking for over 4 years at this point...I really just dont feel sexy to him anymore... I dont see the same type of passion in his eyes.....but ya know what, whatever......maybe I'm just being insecure. :-/
