Some would advocate for gathering as much evidence as you can, then confronting him with the evidence. Because cheaters only admit to what they've been caught with, the more concrete proof he can't weasel out of or explain away, the better. Meanwhile, read my post on STDs. Do not put yourself at further risk. Get tested!

You know some men like to cheat It sucks really it's just sickened toxic. If he after more than one girl than he just into sex sex sex and more sex sorry to break it too you or maybe he has sex addiction problem. If he had affair with another woman maybe he wasn't pleased to be with you and he was very unhappy but that doesn't mean he can't hurt you. He will hurt you with his cheating and have affairs with so many women can risk of infections, diseases, HPV, HIV, cancer perhaps especially ones that smoke more too. If he threatened you in any way I would call police or tell someone you trust definitely. Has he ever abused you or force you to have sex too?

If he gets caught cheating it can be reported by other women and if he had a three some that would be so gross. He will get caught if he gets so much exposed online or some evidence are easy to catch like video of him and her. Well I hope you find a way that can help you solve the case. Good luck and sorry about your relationship. You deserve a better man but if not want another you don't need a man anyways sometimes it takes away freedom from girl time.

Does the acquaintance know that he's married? Does his facebook profile show you both together? You have access to his account, so I would suggest confronting him sooner rather than later, as it doesn't sound like this has gone anywhere...yet. If he then locks down his facebook and start getting more secretive...then you know between what you've already seen and his actions after being confronted what his intentions are. I'm sorry you're in this situation. I wouldn't suggest waiting and gathering evidence unless you suspect something has already happened. If you wait to gather evidence without knowing anything has happened....you'll eventually just find yourself watching it happen, and it becomes even harder to make a decision on what to do next. Stop it now, deal with whatever problems he has with the marriage now before he uses his perceptions to justify what he's doing. Wish you well...hang in there.

I agree with lookingforclosure. Not sure if some of the others are trolls. I would make sure you are covered though just in case things blow up when you confront him. You need to make sure you know your family finances, where the accounts are, how much is in them, and all about his pension/retirement accounts. It sounds like you caught things early - which is good - I hope you can save your marriage.

I'm sorry to hear this is happening to you. I would search now for as much evidence as possible, then confront him with what you've found. Chances are there's a lot more chat and messaging between them. I'd also check his phone to see what kind of activity there is.

Waiting is a really hard thing to do, because you become suspicious of every little thing and most of the time it's nothing, and you end up looking the fool. Take charge now, find everything you can, dig hard and if there's something he's hiding you'll find it.

Once you confront him, I'd ask him to show you all of his digital devices, phone, etc., so you can see for yourself what the truth is, instead of relying on him, as cheaters will lie to they're blue in the face. He will only admit to what he's been caught with, so be sure before you approach him, as he will deny and call them acquaintances. I'd also ask him to delete his fb account, and any other platform used to perpetrate his infidelity.

I wish you well.

Download a key-logger. Inexpensive and you get a report hourly of every keystroke. It sucks to have to do it but you get the truth. Much cheaper than a private investigator and every bit as effective. Remember, you're going to see things that can't be unseen. Good luck to you.

I would give it like a week or so to tell him. That way you can get more evidence if its a EA or a PH or both. He will probably deny it but if you screen shoot everything to show him when he tries to deny it. You will have your proof and decide what you want to do from there. Doesn't matter if he tries to butter you up afterwords. You know what he's doing and will know if its going to hurt you later on down the line or if its an easy issue to sweep under the rug. Only you know. Good luck with everything out there.
