I feel ridiculous even posting this and I don't know why I'm bothered but here goes.
5 years ago I was seeing a guy for 6 months,started off really nice but then his true colours showed and I called it quits.
Me and my friend have been friends for over 15 years.
She only knew him to say hi to with me and had no dealings with my ex other than through me.
Only met a few times.
She sent me a screenshot of him sending her a Facebook request last night,I asked if she accepted and she did,she said that she might as well.
She said they had started talking on tinder and they've been liking each other's pics on Facebook etc.
I know it's stupid but this bothers me,not because I have any feelings for him (honestly he's vile) but she's my best friend yet she's willing to give him the time of day,when she knows he didn't treat me well.
Am I being stupid?
