I will not tolerate any form of gaslighting, abuse, etc

To make a long story short, me and this “friend” (I’ll call them Alice) met on a website about a year ago. It was a website that frequently discussed suicide, so we were both mentally unstable. We connected and then moved off the site to a chatting app

They were great support and always listened to me regarding my problems. The main issue was their views on vaccination (they were more anti vaccine and I’m more pro vaccine). They were into conspiracy theories and believed that their opinion was right. 

I was always scared to boldly state my opinion as they were very adamant about their own. But today, I told them how I felt honestly. And they responded by saying we should part ways and that they are going to commit suicide next year. I told them how upset I was that they cut me off, and told them goodbye. They then tried to gaslight me back into the friendship but I played the pro move and deleted my account. I will not be dealing with them any longer.

I have experienced so much abuse in my childhood, teenage hood, and adulthood. Abusive people, manipulation, and so on. I will not let myself be abused no longer. She will never be allowed back in my life.
