text: can you just sleep with someone? i have been in an on/off relationship with this man for the last 2yrs.  he says its only sex, but i think there is more, so is it possible he is just in it for the sex? is this a question?  if he just wants sex, then you don't belong together.  if he just wants sex, then you are not in a relationship. you are sex buddies.  if you want a relationship, go find one.  when you find someone interesting, have one last hurrah with your sex buddy and tell him it's been fun.  but if you can't help feeling committed to a man who doesn't care about you, then you're going to get yourself hurt. so stop sleeping with him.
