I've heard many times that women are sometimes "too busy" to want to date someone. It's not that they don't like the guy, but apparently it is too much for them emotionally to handle at the moment. I'm in my mid 20's and this has happened on a few occasions. Usually the women ended up contacting me again a month or two later wanting to get to know me. Maybe not "dating", but at least going towards that.
My question for women: is this really true? Are my assumptions correct?
If so, could you explain why women are like this?

My question also stems from the fact that it appears it's happening again, since I tried to pursue a woman that had too many things going on. I am able to see her once a week, but where I see her I would probably have to approach her myself. I don't want to be "pushy", but if she's "not busy" anymore, I would like to be able to keep my foot in the door per say. It has been 2 months since she turned me down.
Question: If I approach her and just have friendly conversation for a few minutes...is that appropiate? Any opinions welcome.
