Affiliate Marketing Secrets

What is it with guys who compliment you, say you’re gorgeous, say they think you’re an amazing person – but don’t want to be romantically affiliated with you? I’ve liked a guy for a while and we’re good friends, we flirt a lot but it’s like I’m just sort of a fun thing for him. No, we’re not friends with benefits at all…
I seem to have trouble attracting a guy who truly wants to be with me. There have been many guys who have either tried to look for more with me (I always turn those down, I’m not easy) or have said they think I’m amazing or beautiful, but none ask me out.
This trend is worrying me – like I’m impossible to love. Can any one help me out? (And please don’t say I must be easy because I’m not. I’m actually a virgin – anytime I’ve been near having sex has been too early in a relationship (ie one night stands) and I’m not down with that.
Does anyone know what the issue is?! Am I just one of those unlucky-in-love types? People may suggest it’s something to do with me, but doesn’t anyone have faults? Even the most horrible person I know can seem to get dates.
