Normal Feelings re: Ex-GF?

[LeVoodoo]

This girl broke up with me two months ago (four months after we got back together - i had dumped her last fall). We still talk to and see eachother on a weekly basis. We've talked about getting back together, it's on the back burner for now.

When we're not together, really the only times she is on my mind is when I think of her sexually. I don't think of the vacations, the dinners, the talks or the good times we had. I just think of her intimately (SIIHP!). Is it normal to think of an ex, that you may still have feelings for, in only this way?

Maybe I want her back for the wrong reasons. Or maybe I am just undersexed.
