What is the best way to break up w/a BF you love deeply? Problem is that he lies & won't get off the online dating sites.

Tell him he doesn't need dating sites when he has you, and you won't accept it. If you want to give him a chance tell him it's the sites or you. You could email eharmony and chemistry and tell customer service the member at his email address is married (even though you aren't), they will delete him. Tell them you are his wife and found it on his credit card or call customer service and tell them on the phone.

Leave him. If he has you and is looking elsewhere, it is cheating. Don't wait until he meets someone and has a relationship with them to leave him. Nor should you wait until he just find someone; you need to move on. Trust me, I have been in a relationship with a man like that. no matter how beautiful or wonderful of a character you have, a cheater will never be happy... it's not you, but it is you that decides to stay or leave. I hope you leave...

"Honey, this isn't working out. See ya."

take him to a realy bad movie make him pay when u get in sit for 10min then say we are breaking up and leave so he payed 20 $ for nothin and u sorta get revenge or u can make him buy u something exspencive.

If you love and respect yourself enough, it won't be any problem, because you will demand love and respect in return from a partner and won't settle for anything less.
