Would you feel betrayed by this?

I would be glad that my son had a seemingly healthy relationship with his father. But also hurt, yes.

Betrayed and furious!!!

Yeah ..i would be immensely hurt and devastated and if you feel so you are not wrong ..i firmly believe no matter how sour one 's relationship becomes nobody has the right to cheat ..to break up is absolutely fine but to break the holy faith of loyalty is , i believe an act of sin .You are not wrong at all to feel betrayed when mutual friends liked that photo ..it shows how much of friends were they ..QUICK NOTE:-They are bastards.they are appreciating an act of sin ( cheating) and hence i believe are also wrong doers ..maybe the relationship broke due to factors contributed by both but you are 0% responsible for the fact that your husband cheated on you ..He cheated because he was and is a douchebag and same with his gf but keep calm ..KARMA is a bitch and it will hit them sooner or later .
Do maintain a healthy relationship with your son .YOU ARE HIS MOTHER AND NOBODY CAN SNATCH HIM FROM YOU .He is yours ..love him ..he is maybe young( considering your age) but when he learns how to use his discretion ..he will stand with you .

I think I would be happy that I have a son to love and apparently an ex that cares enough to utilize his time making our son happy. Honestly life is too short and instead of feeling betrayed be thankful he still wants to be in his son's life. Post photos of your son having a great time with you and your new partner too. Ex can be thankful that he chose a loving woman to be his son's mother too.

I might feel betrayed but that doesn’t make it real betrayal.

Are people supposed to stop caring about other people because they break up with someone?

I know it’s painful, but reminiscing about what you had will get you no where with him or your son or yourself. Stop remembering what you once had.

You don’t know if this new relationship will last or not, but it is over. Do not believe in it out of a sense of loyalty. Find someone with whom you can be loved and whom you can also love. Or find something to do that you are passionate about. Do not let your passion have anything to do with your past with him.

It’s a momentary joy-to remember the past —be carful not to be addicted to the emotional past memories by replaying them. It will keep you trapped in the past.—
With sincerity from my emotional break ups to yours-

When I divorced the second ex, he and the girlfriend with whom he cheated on me used to show up and take my son for visits. It was all horrible, every bit of it. Typically your mutual friends will not want to be forced to choose between you and your ex. It is not fair that your husband did what he did, not to you, nor to your mutual friends. He put everyone in a horribly awkward situation.

You will find that it is better, and healthier for you, not to be offended by small things like friends "liking" a photo. You don't know if they are liking the fact that your son is adorable, and that he continues to have a great relationship with your ex.

Nothing will make this better except the passage of time. But I do think you should reserve feelings like betrayal for more important things than liking a photo.

Hurt

Yes I would feel betrayed and it would cut like a knife, but I would hope in time it would become easier. It's all part of the process

@wildbill83 I understand this would be extremely painful for you. But I wouldn’t look at it and go out and live your best life.

Bruh this is why I have trust issues

Life's too short for something so petty.
You have enough to hate him for without dragging those close to you into that.

It's probably a great photo of your Son. THAT'S what folk are 'liking'.

I would be sad and a little heart broken that It wasn’t me they were with, but not betrayed.

I can see why that would make you severely unhappy, but that's not even in the ballpark of betrayal.

I'd pour a double Jack, with Seven back.🥃🥃

I'd be really hurt... But u got to move on.

A kid will not able to understand your feelings. I guess no mutual friend would.

You said, 'relationship ended 6 months ago'. It's painful but accept the truth, otherwise it would be more painful for you.

Fine

i might become a serial killer but i wouldn't cause of my child's happiness!
