I caught DP using a chat website with the purpose of anonymously sexting other women. When I caught him out he then came clean and told the truth, gave me his login to the site etc.
I said I could potentially work through it provided he did certain things. This involved therapy (which he now goes to) and restrictions on his phone use. As he hid the app / website very sneakily on his phone so no evidence would exist he allowed me to put up restrictions on using his phone and what he did behind my back. In return, I said that slowly I will try to trust him again and if I can't then we know that we can't go on.
The worst part and a big reason for my staying is just before we moved into a very expensive house, I had a bad feeling and told him. He swore that he had not done anything untoward - he was lying and he we are 4 months into our new home.
Now the issue has stemmed from DP not being allowed to use his phone as and when he wants. He doesn't need it for work and uses a laptop all day anyway for what he enjoys doing (horse racing). He still talks to his friends but his phone usage has gone from 7 hours a day (it was always an issue) to 1 hour.
But if there's a disagreement or an argument about something else he has now gone to say "why should I do it" and picks up his phone, threatening to go on the apps that make me anxious (not the chat thing) and turns nasty. I've realised that I am heavily relying on good faith to stay in this relationship, because he throws me into an anxious mess when he does that.
I am 26 and we have no children. He refuses to leave the house despite what he's done. I don't know what to do but please talk some sense into me.
I've not told anyone irl what's happened
