text: my boyfriend sneaks looks at his ex girlfriend? he doesn't look at any other girls but his ex, he checks her out and sometimes stares but tries not to make it obvious when i am there. i still see this though. when he sees her talking to other guys, he grabs my hand really quick, and i think he tries to listen onto their conversation..she is also gorgeous..i am not as pretty as her. it sounds like he might still be hung up on his ex, but that isn't necessarily a death sentence for your relationship.  it is a cause for concern, however.  you should talk to him about it, tell him it concerns you because you wonder if he's still in love with her.  approach the matter cautiously and without being judgmental, as it's a sensitive topic.  and don't worry about how pretty she is.  in the long run, a lasting relationship needs mutual attraction, but even being a supermodel isn't enough to hold a relationship together all by itself.  and remember, there's a reason they broke up!
