Men! What do they want?

Shelley
Do any of you find it hard to date or just plain be in a relationship? I mean I find men to be very judgmental about my weight and height. They will tell me I'm pretty, smart, nice, etc...but remain uninterested as far as a relationship goes. 
I'm a tall girl (5'11'') and am overweight. I'm not Jabba The Hut...So what gives?? What do they want from us?
Have I just not met the right one??
