I have been dating my partner for 5 years and we have a 18 month old. I am also 3 months pregnant with our second. Recently I found explicit photos on his phone and after doing some digging, I found he had downloaded multiple dating apps and uses explicit video chat rooms. I am completely devastated. I confronted him and he told me he was stupid and only done it for some excitement. I told him I found a betrayal and for me it's basically cheating. ( I found out in first pregnancy that he has cheated several times when we were in a long distance relationship for the first year of our relationship). This has really knocked my trust again. He stays up to the early morning and I know what he is up to. I took his phone this morning and found he has been using the apps again, but then deletes them, so if I use his phone I don't see them. We are in self isolation because of the coronavirus so I can't just leave. I feel so isolated and I have no where to go or anyone I can talk to....
