It sounds like you've had a lot of painful experiences in your friendships with women, and I'm sorry to hear that. I do think it's going to be healthiest to try and be a bit less invested in the relationships these women have. As I said earlier, no one is having a relationship with someone else as an action against you, and I think framing it that way is going to be an unhealthy outlook. It can absolutely be sad and painful and frustrating; I am not trying to minimize that. But in this case with your friend, if she doesn't want to talk about her relationship with you, or she's uncomfortable with you trying to make deductions based on what she shares on social media, that's her right. It isn't what you want, but she's allowed to feel that way.
