Yep, my best friend if 15 years literally turned on me overnight. I thought of her like the sister I never had.
When I split up with my ex (my sons dad) she was there and helped so much. I did the same when it happened to her too.
She had a jealous streak in her and she wasn't on my side most of the time towards the end. Didn't like me having other friends other than her. Didn't like the fact I'd gone to Uni, didn't like the fact I still worked because in her eyes I should claim benefits and not work because I was a single mum - basically she wanted me at her beck and call and not have a lovely away from her.
She would try and sabotage any relationship that was developing between me and whoever by looking them up on Facebook and messaging them! I started something up with an old school friend and she jumped in and wrecked it
When she met her now husband, I was casted aside, she had no time for me (her words) and didn't need me as much....
We then just parted, she deleted me off her Facebook and that was that.
The best thing is my life blossomed without her, sometimes you do just outgrow somebody and they are not for you anymore.
She saw my Mum the other week (it's been 9 years) and she said that life got in the way of our friendship which made me so angry! She ditched me for her husband 🤣
