I have been with my partner for a year. We live together and I am 5 months pregnant with our first child.
Recently he left his email inbox open on his laptop and I noticed he was receiving a lot of email notifications from Match.com. I've never seen him get them before. I knew he used to use dating sites couple years before we met (we met in real life). I never thought much about it, we have been in a committed relationship and planning future together. But the sudden influx of these email made me think he must have recently become active on that site again.
So I created a fake profile and set location and age parameters- and yes he's there. His profile looks old- old photos, scarce info and it even says he's 'looking for a real relationship'- I do believe it's profile from his old online dating days. But he's been logging in recently.
I didn't tell him about my fake profile. I only told him that I've seen his inbox accidentally and saw the influx of Match emails. I asked him- are you active on it? Are you unhappy and seeing anyone behind my back? He denied repeatedly and said it's spam from his old dating days, they just keep sending these emails automatically. He repeatedly assured me and swore to God he's not seeing anyone else, he only wants me and has never and will never go behind my back. He said he would unsubscribe from these emails.
That was 2 weeks ago. Ive been monitoring his login activity on the site since - he still logs in every 3 days or so.
So he lied about not having an active profile and not only didnt unsubscribe but still checks the site out regularly. He's a good and caring partner otherwise and I love him. He works corner from home and is back home right after work, I don't see him disappearing or going out- except with his child from previous relationship. If i confronted him, demanded to see his profile and got the worst kind of answers- i would need to move out while pregnant and go through housing hell/ temporary accomodation etc... im a low earner w/o savings.
Turn blind eye and observe? Thoughts?
