Don't mean to burst your bubble, but she probably isn't interested in you; except for a friend.

Its usually the male figures in a relationship that "can't" do long term relationships. Mainly due to the need for direct physical contact (honesty hurts, sorry). However, woman pride themselves on being able to maintain a "emotional" relationship, so they are less likely to turn a long distance relationship down.

She is most likely just keeping you there for a pillow to fall back on. She probably has another person she's more interested in and is keeping you on recall in case that person can't be with her. That or she's just uniterested.

Woman don't like putting people down and making them feel bad, so in turn, we accidentally lead them on.

Sorry no offense. But I give my honest opinion and views. I'm not going to sugar coat things. You came with a question, I supplied and answer.
