Dating Sites Reviews Forums

Hi, would really appreciate some help here if anyone knows please. Been dating guy for around 8 months no real problems BUT I had a gut feeling something was not right months ago. A friend checked his account for me and he had logged in past 24 hours. I didn't act on it but decided to check again the other day. Yes, I sound nuts but created another account and have been checking. Apart from one time where he had checked within 48 hours it's normally within past 24 hours. However I have never actually seen him on line. It see,s he checks in the mornings and is on for like a minute when his profile suddenly becomes higher up in the list. He did mention something about having the app open months ago and looking like he was on but hey it's clearly still happening! I could understand if he was on trawling the site or changing his profile but doesn't seem to be. We've booked trips abroad etc, I'm taking it slow and after years in a bad marriage I can do without problems. Can anyone shed some light or is it just as it looks, he's still looking despite saying he was not paying for site anymore. Incidentally, if I check in my iPad rather than phone he does not come up in the first twelve as being last logged in. cant understand why someone would seemingly go on for a minute! Thanks and confused!
