Ok...
So I've been dating this guy for 3 years now, he told me about his diaper fetish in the first 8 months we were together, first time I didn't agree with it as I had never come across it before, then a few months later he brought it up again telling me it was something he was in to, so I participated in it with him. At first i enjoyed it and seeing how he gets with them made me ..... Well very happy aswell lol. It was fine up until a few months back, it felt to me like this would be the only thing that "satisfies" him and I've stopped enjoying it, as soon as we get down to it and he mention "do you want to put something on" I am not in the mood anymore. I have tried to see it from his point if view but all he tells me is that it feels good, I can't understand why he enjoys it that much. He is on diaper websites pretty much everyday, I knew this but now he had stated deleting his history and it's making me feel like he is hiding more then he's letting on to.
I'm not stopping him from doing it, but recently I have found a secrecy stash of pull ups which he didn't tell me about, also I have found out he had been talking to other girls online with intimate details. It had shocked me more then anything because we don't hide things from each other, or that's what I thought anyway, whenever I confront him about something it seems he will only say things that I want to hear. The thing that had upset me most is that he is talking to girls online, he doesn't know I know, maybe it's just me but I do consider it cheating even though it's online.
I may be acting insecure but after bring screwed over in the past by previous relationships I thought this was the real deal, so to find this out I am shocked and hurt more then anything. I do believe he is addicted although he Denies it, but I don't know how to approach him about it to get the truth. Any advice will be greatly appreciated?!
I do apologise if this doesn't make sense, I have tried to add as much detail as I can but there is still more things, these are my main concerns, I just don't know how to deal with it or whether this relationship won't work as I can't give him what he enjoys
