Help po need clarification

Ung asawa ko po may mga posts and conversations about a guy and she was with their "group" a couple of times stating na reunion gig lang. The conversations state na may relasyon sila at may mga skype video chats pa without me knowing it. There was even an advice from her friend "d2 ka na matulog sa amin at wag na dun kela ****,Baka mabuntis ka nun" There are a lot of conversations and posts between them which pretenses a relationship on going between the said parties knowing that they know my wife is already married but she continues doing the said communications. My question is that is there anything i can do? I've been killing myself with work and then finding this out. Are there any charges that can be filed since adultery specifically states that there needs to be an intercourse or should be staying on the same house acting as husband and wife. She was only able to stay and be with the person for 3 instances. 1 full day and then another 2 days for the 2nd meetup for the said "GIMIKS". When I confronted her she then said that everything was a game for the guy to be able to get his current girlfriend back which is highly unlikely due to a different scenario which is in another story. Need your help. I dont want to end up wasting all my time and effort just to be played like this. TIA

Adultery is a criminal offense and the degree of proof required to have a conviction is guilt beyond reasonable doubt. Yung mga nabanggit mo may not be sufficient para maconvict sila. May isang kaso nga, nakita silang pumunta sa hotel ng paramour nya. Pero sabi ng court,  that is not conclusive na may intercourse. So they were acquitted. Ang pinakamagandang proof ng adultery is pregnancy of the wife with proof na hindi yung husband ang ama ng bata.
