NC as DP knows I use MN regularly.
Long story short, I was using DPs phone a few nights ago and found he was using an international penpal website. I questioned him about it and he said he was using it to talk to people about his hobby. He didn't sound too convincing, so that evening I had a look through his email account and managed to find his login for this penpal site.
On there he had hundreds of messages to other women (just women) some of which were just general chit chat. However he has one woman on there who he emails via the site and his personal email. He has said things to her like he's unhappy in our relationship, he's only living with me until he can afford to more out as 'it's better for our two children' as well as lots of intimate conversations.
He also makes reference to an app called Kik which it looks like he uses to message some of these women, however I can't work out his password. He has been asking these women to send photos of themselves and has commented on their photos/ bodies in these emails.
I'm absolutely devastated. We've been together the best part of 10years, have 2 children (6 and almost 1) and, as far as I believed, he was very happy in our relationship. He has told these women so many lies about me and our life to make it look like he's really miserable so that they comfort him in their messages and so that he can be flirty towards them.
I don't even know what I'm asking really, I just need to get this off my chest as I don't have any close friends in RL to talk to and I really don't want to say anything to my family, although my gut instinct is to expose his lies and conversations. I am just in complete shock. Is this an EA? I really have no idea what to say or do.
