My friends want to attend my ex husbands wedding,should i be mad?

The fault lines caused by break-ups extend far beyond having to divide up objects and finances.

A couple's mutual friends are also often affected and put in a delicate position.

Because it's a tricky to strike the right balance between being supportive, but also not taking sides.

Sometimes, it's impossible to avoid betraying a friend's feelings altogether. Other times, it's a little less clear cut.

One mum is currently feeling as if her friends have crossed a line with her ex-husband, and is asking if feeling betrayed is normal.

See what you think.

"Am I being unreasonable?"

"My ex-husband is getting remarried next year," begins the ‘Mumsnet’ user. "He is marrying the woman who he had an affair with when we were married.

"This isn't the issue. As far as I'm concerned she is more than welcome to him and my two daughters love her.

"The issue is that he has invited two friends of mine to the wedding.

"These happen to be two of my closest friends who saw me at my weakest and most broken-hearted when he first left me.

"He treated me very badly both in our marriage and for a while afterwards and they were there through it all.

"They used to be mutual friends to both me and my ex but have only recently started being back in contact with him.

The two friends have helped the mum through some dark times

"Am I being unreasonable to feel betrayed? I know they are adults and they can make their own decisions and if they want to go they have every right. Please help me!"

While one mum counselled a 'live and let live' attitude, others were unanimous - the mum had every right to feel upset.

"Have they said they are going?" asked Olivia Benson. "I'd have to rethink my relationship with them if so."

"They have no reason to have to have him in their life," pointed out another mum. "Give them the opportunity to say no before you say anything to them."

However Giselaw suggested there was no reason for the invite to cause any strife, and even suggested the mum should move on.

The mum has been pushed to ask for advice

"You may not be able to see past the personal hurt he's caused but doesn't mean everyone else can't either."

It's sound advice, but in light of the mum's update that her friends were going to go, her feelings of betrayal have only gotten deeper.

However the mum chooses to react, the wedding invite situation proves how far-reaching the pain of a break-up can be.
