Those longing stares into each others' eyes are not bull-- you two really have something and you shouldn't let your neuroses and jealousy get in the way. Of course, s/he'll be talking to other guys/girls-- s/he's allowed to be friends with other people, right? If you become to concerned with how your current bf/gf is around anyone else, s/he's not going to be able to put up with your irrational ways and you could loose him/her. Trust that what you have is special and that nothing could come between you-- if you don't, that's when the trouble will start.
