if your sleeping with the second guy, you would have to stop. this can cause you to be even more confused. you have to tell him you feel guilty and you have to sort out your feelings.
in a relationship you have to constantly work on it. it may be exciting one year and dull the next. having two men in your face i m sure your constantly comparing and this is not fair.
we cant make that decision for you, but you have to clear your head and figure out what you want, you cant play both sides, you have to make your mind up.
my advice is, be sure of what man you want.
my ex broke up with me after five years together. now it's been two years after our separation and i m in a happy healthy relationship, and he cries to me on myspace about how horrible his girlfriend is treating him. my response to him was i dont care to hear it. it treated me bad because he wanted to be with this women, now he wants to cry to me about how horrible she is.lol
