Am I cheating on DH?

[Batcrazymum3]

really don't feel like I am but it would be good to get some opinions about this.

I have just returned to work after 1 year of mat leave after having 3rd (and final) DC. It's been so good to be back at work and to catch up with everyone and the adult conversation. One of my colleagues who I have always had a very good working relationship with had been dropping me emails daily just checking in making sure I was getting back on track, the emails went from being casual work chat to a bit more personal. As I am only part time now, one of the days I came in to an email from this guy saying that he missed me when I was gone and that it made his day go slower when he didn't have me to talk to, this led to us exchanging numbers.

The chat is flirty, it's completely harmless but I keep deleting the thread of texts. Only once did the messages go into... let's say dark territory and it was quickly laughed off and it's never even come close again.

I love DH so much, We have an amazing life, our sex life is fantastic and he is very much my best friend. It's only now that I'm writing this I'm not actually sure what I'm asking for. I must feel guilty on some sort of level if I need someone to tell what I am doing isn't wrong!

What would you do if your colleague shared those texts with others. You're deleting your chat history, maybe he's saving his. What would be the fallout at work, even 'informally', with other colleagues and how would this affect your reputation?

yes its a start of an emotional affair, which may or may not become .physical
My DH works witha group of men and this girl joined the group they work on a film set Shes much younger but nothing toworry about at first.Then I noticed her namecroppingup then suddenly nothing then found out they were pm each otherinstead of using the group wattsup he never let his phone out of sight all of a sudden. Thenthey were on snapchat(Just to send funny pics)??/ this is someone who barely knew how to use an iphone. He deleated his emails etc. #Anyway it came to a head when she snapchatted 10pm on non workingdayAccording to him what would she see in him,hes much older etc only workmates. As I pointed out he is working with 200 0ther women on set yet doesnt have them on watsup and snapchat,Anyway caughta few lies out dont really think itwas much more than a crush on his side and he loved his ego being stroked, she on the other hand is dangerous.She over chatswith all the non single men.He closed down everything she could contact him on. He still doesnt get that it was an emotionalaffair. My daughters who tore into him about upsetting me dont want tocall it that but itwas an emotional affair and though we have sorted things out I am dreading them being back working together in the Autumn.She delibrately tries to get his attention onthe work watsup so have told him to pull her up or I will.
So be very careful if you have to delete something that isnt wrong why would you???Would you like your hubby doing it?
