I had a 'friendship' exactly as you describe it in college, he'd tell me how wonderful I was and what an amazing person I was. He'd date other people, but he'd be back with me at night (that sounds a lot dirtier than it should - we were never sexual). The reason he couldn't date wonderful me? No attraction - I wasn't skinny enough for him. That did wonders for my self-confidence. Once I was away from him (b/c of cir stance) I was happier and it was amazing how much better my life was. No more pain, no more lingering uncertainty, no more damaged self-esteem (that quickly became reliant on him for everything), no more lying to myself about how I felt and what I wanted out of the relationship just to be able to be with him.
