Ex defriending co-friends?

[jnr1005]

So my ex and I had a rough split..his choice to leave after 2 years.. broke up with me and my 2 kids (wants no contact with any of us.. even ditched the dog that he paid lots of money for.) 5 days after split he goes on date with girl and is now seeing her..so you would think he has moved on. So we have a few mutual friends..one of his guy friends that helped him move and that I know felt bad that ex told my daughter he "might" come to her recital even though friend and I knew he wouldn't.

It's been a month, and friend being the nice guy he is tells my daughter he will come to recital. I personally would not have told ex, but friend figures he should be able to hang with either of us and not have to hide it, so he tells ex...and ex went ballistic. I guess they got in a huge fight..even when friend assured ex that this was just to be nice to the kids and to hang with me..strickly platonic. (no interest there what so ever..to be clear). Next day friend calls me and tells me he has been "defriended" by ex. Both of us are kind of confused on why ex is being so imature.

So what do you think? I mean if he has moved on with new girl you would think us having a mutual friend would be no problem..right? I am trying to figure out if it is poss painful to be reminded of me or if you think it is just "I am with new person and want no one that knows you" kinda thing. I do feel bad about it, because the two of them hung out a lot, but I never asked his friend to do this, he offered bc he felt bad for the kids bc they took my ex leaving so hard. (The 4 yr old thought of ex as a dad.)

I mean I would not defriend my girlfriend if she hung out with ex (or his kids if he had any)..now if she was dating him maybe a diff story, but his friend and I are just friends..not even really close, but cool to hang with. Ex blocked me on FB which I expected, but this was weird and seems imature. (Ex is 25 and I am 28 for age ref.)

You ever heard of the saying "Bros before Hoes" Possibbly your ex feels betrayed that the mutual friend invited himself into you and your childrens company without asking him if it was okay first. Possibly thinking that he was trying to take over where ex left off?
Your friend obviously didn't get "permission" from your ex and therefore he put you before the brotherhood.

Some guys care about a friend stepping into their territory even if they no longer hold the deed or right to ownership. I suggest you stop worrying about what your ex thinks does or obsesses about. Who cares about his shit is the new motto.

It's a slippery slope a few of my friends are still friends with my ex which is quite painful for me but I know why they are still friends we were all close but I would never ditch my friends for hanging out with her. Yeah all of them are platonic. I really would stop worrying about it. I mean if my "friend" ditched me for because I was hanging out with somebody they didn't want me to then I wouldn't consider them a friend
