I have a strong suspicion that my dp is either cheating on me or addicted to porn. He may also be looking up various dubious websites eg escorts.
The problem is I have no proof and if I try to speak to him, he makes me think I'm going crazy. The other night I came downstairs at 2am when he had said he would come up to bed at 12. I heard him slam his laptop shut and he also had a blanket around him. He jumped up really quickly after went past him and looked extremely guilty. However, when I confronted him the next day he insisted he was just playing a computer game and only looked guilty as he knew he should have already been in bed (I'm not his mother so don't see his point about this).
In the early days of our relationship he told me he uses incognito tabs when watching porn. He also told me that when 'out with the lads' he had visited strip clubs and met up with hookers in Amsterdam (although hadn't slept with any). He says he was much younger then and would never do that now. His brother's stag do is in a couple of weeks and I'm very nervous.
Is there any way I can check up on him as don't want to accuse him in the wrong. I'm clinging on to the hope I might be wrong and I don't entirely trust my gut instinct. He works in IT so i would assume he is very clever at covering his tracks if he is up to anything.
