UPDATE Boyfriend away... Do I check the computer

Previously found him messaging other women and lots of pics on his phone.....swore would never do it again.... Still have a gut feeling something's up. Shall I check the computer whilst he is away- he has his WhatsApp linked but worried it's linked to his phone but he did mention once registered items in the flat doesn't require 2 point authentication.

No I don't trust him but I feel I need proof as otherwise, based off last time he will initially lie until I provide evidence. I will be discussing with him this weekend that I don't trust him and will ask to go through his phone and if he doesn't hand it over that's my answer. I would still like some idea of what's going on.

For all I know it could be fine but also gut feeling going to find something bad.

UPDATE

I never checked and instead told him how I feel and why and we are discussing it tonight. I will ask to look through his phone if I feel he is lying and if he doesn't I'm gone.
