DH has always been a big gamer, which hasn't ever been a problem. More recently it's come to light all the time I thought he was "gaming with the boys" he was actually with some girl online. Getting up to all sorts. There were times where he would send me off to my friends and make out he was doing me a favour and clean the house and cook for example but little did I realise this is when he would also be videocalling. This all came to light simply because I realised all the conversations were over something called Discord. Which I never even knew existed. We have 2 children together and now I'm really lost. He has never been unfaithful and has told me it was silly and a fantasy thing because they developed a bond over gaming. He doesn't even talk about completely removing her from his life and says he will obviously only play in the future, which is ridiculous, if we continue the marriage then of course he needs to drop her entirely but I don't know if this is something that could be forgiven
