if you loose feelings for the person you are currently with i say yes... but make sure u realy like that person cause you're probably going to fall for someone else when you go with the new girl and dump her for a new one and so on....
hmm i've done it before quite a while ago... but only because i knew that the relationship was turning sour... and i gues human nature is to be selfish at the end of the day... you want what you want... and you are always striving for something better right?? well in most cases anyways...
It depends on the situation, if things look like theyre gonna end anyway, if sometimes if thats the case, then possibly, but i'd try to work and fix on the current relationship and if it doesnt work, then there's "her".
it all depends if it is easy to get another one. i meant, no one could blame them for cheating because they're attracted to someone else.......they're jsut following their heart. It's a good thing that they dump her/him......things get worst if u keep both, na meen?
