I have delt with ex's boyfriends and husbands. My wifes best friend was in a bad spot. Wouldnt leave her alone. Was with him 4 years allmost 5. Had 2 kids with him. Lived totally off of him. She tried to get out. Had to call the police. Couldnt press charges cause she loved him still. It was bad.
Then one night me and the wife where there. He came over they started to fight. And I went to the door. He thought I was the new guy.
He backed down big time. Didnt want to even talk to me or say hi. Once it got a little worse. I stepped in and told him to leave my girl friend alone. Stepped up and she hugs me sorta... Said dont do anything to hurt him.
He started and I finished. It's been 3 years and never even heard of him since then.
