How do you tell a guy you love him when you just came out of a bad relatshionship with him?

You sound very confused and it would be to your best interest to take time to think of why the two of you brokeup. You said it... 'bad relationship' so it's best to move on. You can do better and there are a lot of nice guys out there. Sometimes people are in love for the sake of love or they are use to the person being around and feel lonely and that's not love!
