If they don't have another person to hang out on v day and has to bug you or drop you hints then you are dating the wrong person.
Make sure all of them have someone else cuz that is what dating in your term is all about. No commitment is just that so help it serve it's duty.
If V day is broke day then times it by how many you have. V day will expose a lot of people eyes out. If you not spending that V day night with them then they are not the one for you. Then again, it is a con game and some women ore men are still that naive. We can celebrate the day after cuz you are my second best, nam yap.
