You guys. I'm pissed.

So my husband and I have had a tough relationship, but we stuck together because we love each other. It's just that the difficult parts aren't simple difficult things. But we love each other and have been together since we were teenagers. Many many years.

About a month or so back I had to use an old phone of his when mine went I. for repairs. I was trying to get set up and noticed he had his personal email still set up on the phone. I went through it because he has a history of being a little too flirty and I just wanted to make sure there was nothing untoward.

WELL.

I found a of emails between him and a lady he used to work with. After squeezing him for information he admitted their relationship could be considered an emotional affair.

I made him send her an email saying their relationship needs to revert to a profrsssional one. Which he did. I even apologised for making him do it because I could see he was sad to do it.

Then we put it behind us.

Today I had to use the phone and lo and behold, an email. Not professional. Personal.

I felt sorry for her because her marriage is in a shambles and she obviously liked the attention my husband gave her. Not anymore. I want to contact her directly and tell her to fuck off.

But I also want to remain cool and collected.

Advise please??
