Please help! Friendship advice needed

I’m so sorry this is so long I just have so much many questions….

I’ve been friends with someone for over ten years, but our friendship has become more of a burden than a source of support. In the past, during a team lunch, our coworkers were complimenting me on my personality and work ethic. My friend, on the other hand, didn’t receive much feedback because she’s very quiet and reserved. Afterward, she expressed her frustration, claiming that the compliments I received were ONLY because i don’t speak up for myself.

This comment hurt me deeply because I do speak up for myself, and I felt misunderstood and unappreciated by someone who is supposed to be my closest friend. This incident isn’t isolated. She often shares her life issues, blaming everyone else without taking accountability for her actions. She rarely acknowledges when she’s wrong and prefers to gossip about negative things. Additionally, she often involves her mom in our business, which makes things even more complicated.

Recently, I rekindled a relationship with my ex, who I broke up with previously due to certain issues. Despite our past, the love was never lost, and he has made significant changes. We’re slowly reconnecting, and things are going well. However, my friend informed me that he follows her on Instagram and liked two of her old pictures. She compared him to the men she dates, suggesting that I don’t know what he’s doing and that he could be liking other girls’ pictures, or being unfaithful. Initially, I was upset, but after talking with him and understanding his intentions, I realized it wasn’t a big deal. He’s a god-fearing, nerdy, and genuinely good person.

On the other hand, my friend dates men with multiple children, and that live unstable/ unhealthy, unchristian lifestyles. She let every man she dates moves in and has a five-year-old child at home who is kind of a bad child and she knows it and willing tell her that she’s bad to her face, like it’s ok and funny. Despite her own choices, she criticized me over something as trivial as my boyfriend liking her pictures. To make matters worse, her mom messaged me on HER Snapchat, cautioning that my boyfriend is manipulating me to get back with me and stating that meeting my dad sends the wrong impression. While I understand she wants me to be careful, I feel I’m already being cautious. My boyfriend met my mom before she passed and wanted to meet my dad to ensure he knows who I am going out with. They have spoken on the phone before, so I don’t understand what the problem is. Our relationship was always leading to Marriage so he’s not just fooling around with me. Yes, we are taking things slow, but we know how we feel about each other and how we see our future together.

I’m at a crossroads now, questioning whether to continue this friendship. I feel drained and unsupported, and I’m not sure what to do next. Has anyone else experienced something similar? How did you handle it? Any advice would be greatly appreciated.
