Totally devastated

I came to work today.
I've been crying all morning and on way to work. I was so distracted while driving, I donno where i was driving sometimes. 
I found this out on Saturday night, i tried calling him at night cos i got nightmare and wanted to talk to him. He kept disconnecting my calls. Out of concern i tried to trace him, and then I found out that he is texting this number and he is not at home. Saturday morning he is talking to me and asha on the phone and email gals for hooking up at the same time. How disgusting. 
He lied to me over and over and over until i have found out what ever i found out until now. I still don't know how much else he is hiding. He has met this gal at night, and tells me he dint have sex. That's not even closely believable. 
I hve to get back to work now. at least try to work. 
I have no idea how i am going to deal with this. i'm totally devastated. But i don't want to lose myself. I want to stay strong, and divorce or not, i want to stay strong. 
Stay strong. Stay strong.
