She said she NEEDED to ghost me

A woman and I have been close friends for 9 years. We live 4 hours apart. She was married when we met and we were friends but were very physical with each other despite never crossing lines overtly. We fell out of touch for a year during which she’s had affairs with four other men then left her husband. She now lives with one of the men she had an affair with.

We always share deep personal information and say I love you.
I visited her recently and I joked about us having a threesome with me and another girl and her eyes lit up. Then over drinks I teasef her about being attracted to me and she looked up at the ceiling and said “no” then looked away and wimpered “stop, please stop.” I just laughed and changed topics.

At the end of the night she
came into my hotel room and kissed me before saying she had to get home to her boyfriend. A few months went by, we’d have 7 hour conversations even a a 12 hour video chat. She asked to make love to me on the phone eventually. I was very chill about it with a “sure.” Then she had a fight with her bf and left her house to stay with a girlfriend then returned to her boyfriend.

My mother became very ill at that time. She loves my family. She talked me through it immediately when I told her.

The day after she turned cold. She stopped talking to me as much, stopped saying she loves me, her tone became irritable and cold over the next 4 weeks.

She’s ghosted me for a month now.

We are linked on every social media platform. She’s linked with my family too. 2 weeks ago she text me an message saying shes sorry but she’s angry at something I said and NEEDED to ghost me.
