Looking back this is my first clue

This happened this morning after she left her Facebook logged in and I have been having a bad vibe about this one guy who came tho my son's birthday party last week because my son plays hockey with his son and my wife always wants to drive him to the hockey practice/game. This seemed suspicious but I didn't think i needed to worry because she likes taking my kids to soccer, hockey, skating which I go to unless one of my younger daughters don't want to go I stay home and watch them.

So I thought I'd snoop and take a look at her private messages and found them making plans while at hockey about what they are going to do. I've confronted calmly and she is just making excuses but I'm not having any of it. This has been going on since September 2018 and she said she was going to tell me last week but she didn't for some reason and she wants to make things work if i still want to, which I don't.

I've provided for our family since my son was born in May 2008. Shortly before she went on maternity leave and we had 3 kids together and she never went back to work since early 2008 and part of our issue was money was always tight and i had to work over time a lot to make ends meet.

I feel so betrayed and shocked and I can't think clearly on what I should be doing to make sure I do everything right for me and my kids. I've exported the Facebook conversation and uploaded to the cloud and have it saved on a few different locations to make sure it is not found. I've emailed a divorce lawyer asking for instructions but she is has an away message. I've also recorded all conversations with her since I found out so all the info I can.

Unfortunately this is a long weekend which sucks that I have to wait till Tuesday to talk to a lawyer. Does anyone else have any other advice for me?

edit: Since this post I opened a new bank account and plan on updating my work auto deposit as soon as I can.
