Alright .. first you must get over your past relationships and not let them be a yardstick or criterion for judging your current relationship.. if you haven't moved on or gotten over your ex then i advise you don't get into another cos you don't wanna hurt someone else just cos you were hurt by another .. if you do that, then you will instead of thinking he is cheating when you call and he doesn't pick consider the possibilities of other things like; maybe he is sleeping or away from his cell phone. hope it helps
