Finally caught the wife cheating!

So I've been suspicious of my wife cheating for years but she is such a good liar.. Every time I get close she throws an alibi to clear herself.. By coincidence, I came across and muni recording device on amazon I bought for 20$ so tiny and holds 3 day charge.. Anyway, I threw it in the bottom of her purse.. And what I heard the next day crushed me.. They met at a condo and had a lovers spat revealing they had a relationship for about 6 years.. All kinds of details like how His wife brings him down and she gets his grumpy mood 🙄.. And of course you can clearly clearly hear them make up and have sex.. So many emotions rushed through my head.. I didn't know how or what to think.. My thoughts were so all over the place that I didn't brake down until the next day..

... Now I've quite the problems ahead.. I've yet to confront her about the proof of for the following reasons..

My 7yr old daughter is Soo excited for Xmas and we made plans to have all of her family at our place for Xmas dinner..

My father is final stages of Parkinson's and just recently fell and fractured his l2 vertebrae.. He can barely walk as it is.. Now he is hardly able to move.. I don't need to put more stress on him..

We have 1 rental property and one dream home we live in now.

She will not want to let go.. And just to "add the cherry" over the years I lost contact with all my friends and only have mutual ones that I can not confide in.. I have no one to vent or talk with to helpe try to figure out what I should do.. 😢 Do I wait until after Xmas for my daughter?? It would crush her.. and all the family.. Or confront her and rip off the Band-Aid.. I'm trying Soo hard to not tell her to f*ck off every time she talks to me.. She still tells me that she loves me.. But zero intimacy.. I'm 3 yrs we had sex twice. I don't know why I put up with it.. I don't know what to do.. If I have the proof now.. 😳
