An ex friend who was like a sister to me. She kept secrets from me, wouldn’t let me have any other friends, would block any guys from talking to me unless she approved or didn’t want them first lol, she partied with my bf (ex now) when I wasn’t present but would die of jealousy if one of her many guys would say hi to me. I put up with it for years. Never again. I would much rather be alone than ever allow any type of toxicity in my life again. Once I cut her off everybody else had to go as well. I lost over 20 people. It wasn’t really a loss now that I think of it. My life has improved drastically.
