Since your "best" friend just went thru this herself, I don't understand how she could possible do this to you!! Can't she SEE what she's doing?

Can't she SEE that it's the same scenario that SHE just went thru? Is she totally blind??
She has to be either the most IGNORANT person, or else she just plain doesn't care. But either way, stay away from her because she's toxic. She isn't good for your mental health, and neither is your ex. They both are selfish & immature.
Best of luck, and I hope you find a new friend, and a new relationship! Make sure you get to know them VERY well, and that they can be trusted with your life! God bless you & take care.
