I love my best friend and truly wish her the best, but lately, I’ve started to realize that I don’t enjoy spending time with her the way I used to.

It all started gradually about three years ago when I entered a serious relationship. The first incident was when I moved in with my boyfriend, and she came to help. That day, she was acting really strange—making passive-aggressive jokes about my boyfriend—and after we finished moving the furniture, she invited me to go clubbing with her. I was exhausted and declined, and she didn’t take it well.

This year, she had a falling out with her family and asked if she could stay at our place for four days. It was bad timing, but I said yes, of course. From the moment she arrived, she was in a bad mood. She walked in without taking off her shoes, threw her stuff in the middle of our apartment, and constantly complained about everything. I tried not to take it personally since I knew she’d had a rough time with her family. But throughout the four days she stayed with us, she remained in a terrible mood, made passive-aggressive jokes toward my boyfriend, and kept going on about how much she hates men.

I even took her to visit my mom, and she acted the same way. She ruined our New Year’s Eve with her negative energy and ended up picking a fight with my boyfriend.

Every time we hang out, she tries to convince me how awful men are and how much better it is to stay single and go on fancy dates with random guys. While I respect her lifestyle, I’m tired of the constant negativity towards men and relationships.

I feel like if I want to safe this relationship I need to do something but I don’t know what and how ?
