My partner of 10 years has an active profile on a dating website. I found out this weekend when he received an email containing new 'matches' whilst sat next to me. I checked it out prior to confronting him as thought it could be one of these spam type emails but no it is a live profile with a fairly recent picture. Queue me calmly bringing it up, can you tell me why there is a.... And him relaying an embarrassingly stereotypical script ''I don't know. Then, oh I went on there once years ago. Oh right, why a recent picture? It must be pulled from Facebook (obviously it doesn't work like that). Then suddenly he signed up when we were not together. We separated for a short period 4 years ago during which he appeared distraught and wanting reconcilliation. The profile picture is more recent than this. He swears he has done nothing wrong, has no reason to be on a dating site, loves me to death, is fully committed to our future etc. He did briefly try the I can't believe you don't believe me victim card but quickly realised that I was not going to rise to any such gaslighting rubbish and I was going off what was in front of me. It does seem a bit out of context as there has recently been quite a big life event and he has been slightly more anxious than usual but nothing that seemed directed at anything other than this. A few weeks ago there was a period where he seemed more aware of what he was doing on his phone than usual, although this could also have been related to the life event so I didn't think too much of it. He does have form for being unfaithful historically (as in was a bit of a player / insecure type that 'needed to feel wanted' when younger) but not (that I am aware) during our relationship. After I confronted him I left the house. He immediately tried to call, then text with justifications and went onto the profile to remove the picture and amend his 'location' from our home town to somewhere more generic. I am by no means naïve and would like to think I have good boundaries in my relationship. He says he 'would not do anything to jeopardise what we have'. I would like to believe him but don't due to his past behaviour and what is being dangled in front of my nose. Not sure why I am posting... similar stories, reactions?
