Best friend is my worst enemy!!

This girl is the most conniving piece of shit that ever walked this earth. She ruined my life when we were kids starting drama. And I’m the one that went back to her so our kids could grow up. But last night we were together while the guys fished. And today she asked if my husband not going to say names told me what the guys talked about. And she told me my hubby told her hubby that (mine) has been talking to this girl on and off. And that (mine) told (hers) that he jerks off to this page that I deleted. And he wasn’t going out last Saturday because that girl was going to be there and she wanted to have sex with him. And (mine) swore to me it was all a lie. She’s done that in high school where she made up things and ruined friendships. I’m NEVER going to talk to her again. She wanted to ruin my marriage because she doesn’t love her husband and she told me and that he watches porn and he’s not going to stop. I asked the girl and messaged her if it was true. And she said it was not. My husband is the most perfect guy and he’s not like other men. And I think even if he did he sure as hell wouldn’t of told her husband. We barely hangout too. That was the first time in a while too. And a longer time for the guys. So she calls me and asked how we were and I said were fine. Like how can someone be that crazy to think and to make up story so detailed?? I was so upset I hope he never ever cheats on me. Because I did not handle it well at all... he bawled and told me you’re not going to believe me over someone that’s screwed you over multiple times.
