<human>: Can you provide a brief rundown of the text in within 3 sentences?

Earlier post 

Sorry for the bad grammar was not in a good place mentally and English is not my first language.

So after a few days I think I can think things out a little more logically.

I held my wife's hand for the first time in a while today. No spark, nothing there is no love there anymore. I think I want to move foreword with a divorce.

We have three kids together. I don't want to lose custody of they right off the bat or get kicked out of our apartment.

I have evidence that the man my wife is seeing has expressed interest in hurting me. And my wife doesn't think it would be a bad idea expect for the fact that she would have to nurse me back to health.

I got this evidence by looking through her emails and taking picture on my cell phone. There is plenty of evidence of her sending racy picture and video and planed meetup in the past and in the future. Since I looked through her email I don't know if it enough to report to a lawyer or the police or if it was even legal for me to look through her email. 

If it is legal for me to look at her emails is there any program I can install on her computer? A key logger. I need to see if any more threats to me are be circulated. 

If a description of what he wrote to my wife would help with seeing if I have a legitimate cause to get the police involved I with with an edited version. 

How do I go about looking for a lawyer?  Is there an online resource I can use to find one in my area. I don't have much money, I know this can get expensive.

Any and all help would be appreciated
