"Friend"/boyfriend drama

Savannah
My boyfriend and I have been dating for 4 months and he and I are very different people but we have a mutual respect and understanding for each other. I love him so much! Before we started dating, we had this one mutual friend, let's call her Marie. When my bf and I first started dating, Marie had a boyfriend (they're broken up now) but she has always been out to end my relationship. She would tell me all the time I need to break up with him because we're so different. At one point it almost worked but my bf and I talked it out. I learned she was telling me lies about him. I haven't talked to her about him since then because I know she's always going to say how she loves me and she loves him but she doesn't love us together. Anyway, I learned the other day, Marie has been telling my boyfriend that he needs to break up with me because (according to her) he likes me differently than I like him. 🙄 I want to talk to her about it and tell her to leave us alone (preferably in person) but every time I see her now, my stomach drops. I've been so stressed out about it but luckily, my guy is wonderful and reassures me that when it comes to us, he only cares about my opinion. ☺️
Any advice on this situation? Do you think she might like him? Because I'm kinda worried about that...
