Feel like I'm going crazy!

[AnnBann]

Long story short husband was snap chatting new girl at work for a few days, I was suspicious because he never used snap chat properly and all of a sudden he started using it. He said it was innocent but he was being secretive. He knew the girl 2/3 days and he already had her on his Facebook and Snapchat, he says she added most people from work, I think it's weird, it wouldn't be the norm in my workplace anyway.
I think he fancies/fancied her. He deleted his Snapchat.
Anyway he now has a group chat on Facebook, him, 2 other guys and 2 other girls, 1 of whom is the girl in question.

I feel like I'm going crazy, I can't stop thinking about it. I want to check his phone all the time. I'm angry with him all the time. I feel like he's was being deceiving.
We have 2 children and been together 10 years. I've never felt like this before and had no reason to.
Can I ever move on from this?

It's very hard, I would be the same as you, have you tried speaking to him about it and explaining how you feel? X

See I’d be asking why they needed to exchange number for what reason? What decent woman messages a married man after work? Also consider men lie say they single , separated. Sorry If an old female friend or a hobby friend fiend but new female work colleague. Not on. No decent woman would text a married man when he at home with his wife how rude and wrong

Definitely what @FabbyChix has said. To add as well, no decent man would do this either, it really isn't on.
