My guy friend says i'm like a "little sister" but sends me mixed signals! WARNING!! This is a long one!?

Guys suck don't they? Reffering to one you sleep with or kiss as a "little sister" is odd, period. I had a similar experience recently. The "little sister" comment turned me off completely. We are very close, but after that comment I felt as if I was just there filling some void of his. My situations with "My big brother" are similar to yours in some ways. You need to figure out if it's worth it, or is he just going to continue toying with you BECAUSE HE KNOWS HE CAN. He can get what he wants without the commitment. A man's dream. You need to come clean and ask this guy whats up, but do it tactfully. Trust your gut. Don't be a fool. You deserve someone who can man up!!!
