My SO was away working for a month and I found out he was on a dating site, he said it was just so he could make friends with some of the people in the area but his profile said single and he met up with a girl from the site. The conversation I saw was not flirtatious but it still upset me, I found out recently that he still has the profile but he hasn't been logged on since he got home. Ive become very self conscious after having a baby and gained a lot of weight and im still dealing with the stress of it all.
