crazy ex friend

Isa
Alright so here's the story.
A few years ago my husband and I became friends with a neighbor couple. They had a lot of problems and the husband was transitioning to female and their relationship was very strained. The wife started hanging out with us more and more and I genuinely thought she was my best friend. Until, she started doing things that made me uncomfortable. Like calling and chatting with my husband for an hour. Coming over when I wasn't home and little things like that. I told him I wasn't okay with those things but he said I was overreacting. I though okay, maybe I am. But then she asked him to do her a favor and take her to walmart to get her tire changed. He does and bam! She confesses that she loves him and that she would like a relationship. Now it's a he said, she said about what happened after. He says nothing happened. She says they held hands and hugged. I mean no kissing or anything but I cut her out of our lives super quick. Fast forward a few years she meets a new guy, gets pregnant and she wants to come back into our lives. She said she was confused  and  sorry and me like a dummy accept it and try the friendship again. Except I can't trust her so I tell her and I break it off again. That's when she starts telling me the "truth" about that day. How my husband told her he didn't love me and that he didn't have a choice and that he kept trying to kiss her but she didn't let him. And all this nonsense. I trust my husband. But now 4 years later she starts texting my husband asking how we're doing and all that stuff. I just want to tell her to fuck off and I want to text her husband all demand that he tell her to stop. She keeps stirring up drama. I wish she'd just forget about us!
