<human>: We've ben broken up for over a year now, and have hung out a few times more recently. We've had a lot of fun, and we really only broke up because college was ending. Now, she's moved out to my city and we been seeing each other every once and a while. If anything I'm more excited about her now than I was when we were dating.

Unfortunately however, she's gained a good deal of weight. It's been a long slide since before we even broke up, but last time we got naked I couldn't help but be a bit turned off.

What's really unfortunate is that I know she very much wants to get back together as well, and I think that if she somehow got the message about weight she would jump right on it. As it is, I've been totally dodging the issue, since she still hasn't forgiven me for the time I brought it up a couple years ago.

I'm talking about 20-30lbs probably - then she'd be smoking hot! Such a shame since everything else is great! How can I get this message to her!?

Can you summarize the given text in a few sentences?
<bot>: Would get back together with ex, who also wants to get back together, if she lost some weight. But how in gods name do I her that!?
