<human>: Can you condense the text into three sentences or less?

As for myself, I feel I'm in that situation right now.

Mid 20s male, and I've been consistently seeing an early 20s woman. She's fun to be around, similar interests, sex is fun, but I can't see things with her being long term. It's also obvious she's really into me. Some of the issues I have with her are she's a heavy drinker (She also got a DUI recently), and she's a little bit heavier than I'm really attracted to. 

We haven't spoken about anything long term, though I've met her father and he seems to love me. 

She's a great girl for right now, but at what point do I say, "Well, I gave us a shot, but I don't think I'd want to be with you years down the road." 

How would you handle the situation? There are no real deal breakers if she kept the drinking under control and if you exclude my being shallow about her weight; I just know I'm not crazy about her.
<bot>: Having fun with the girl I've been seeing for a few weeks, but I don't really see myself wanting to be with her long term.
