I'll try and keep this short.
Together for years years and have children together including baby.
He has been unfaithful before and I very reluctantly gave him another chance. I suspect that has come back to bite me on the arse.
Last night I walked into the bedroom to find him on his phone, the second I entered the room he locked his screen in a hurry.
I asked what he was doing he said he was setting his alarm clock. I asked why he needed to hide that and lock his phone and his reply was "I don't. I'm not hiding anything" but I could tell by his tone he was flustered. Like a rabbit caught in the head lights.
I didn't ask to see his phone on the spot which I should have done with hindsight because now he's had chance to delete whatever he was hiding.
Now, I won't stand for this shit again and am bracing myself to get rid but I want proof of what he's up to before I kick him out as I'll be leaving myself in a difficult situation with youngest still being a small baby among other things.
If it's something like deleting porn from his history that doesn't bother me, but he knows I'm not bothered about things like that so he needn't try cover his tracks. My gut tells me it's more.
He doesn't really go anywhere other than work (the previous affair was a colleague at previous place of work) so if he is up to something it must be another colleague, or he's bunking off work.
What do I do now?
Please don't immediately jump to LTB, because I will if I'm able to prove my instincts are correct, I just need to know for sure.
