Found him on POF

So i dont know what to do or think.... my boyfriend we have been together for 3 years ...in june i did a scavenger hunt with my work... it wasnt bad or inappropriate at all..this was the time my boyfriend started to make my life hell for a good 3 days he was gone for hours on end... wouldnt text me he threatend me with cheating all this other shit... i went on his email last night cauae something in me knew something may not be right but he has been my rock these past couple months ...i know he loves me he shows it everyday .. he really is a good guy..he told me it was over i didnt take him seriously cause i just found out i was pregnant then we live together and are unseprable... i knew he would never really cheat on me physically... so i seen that the account was made in june when all that shit happend ... i feel like he only did it just to annoy me ...but te fact is he has had it all this time there was no recent activity but the fact he had a picture up were we were together ...his profile saying he was looking for a relationship ect... i dont know how to approach this or take it...cause i know hes not cheating but he has turned this around on me to snooping as i never look through his phone or emails or anything untill i randomly just thought hmm im going to take a look on his email and i so happen to find that...what would you do in this situation...i am 30 weeks our anniversary weekend is this weekend ...we have been so happy he has been my rock ..and has went out of his way ...he has no time or would cheat but the fact he still kept this i find is so disrespectful and that he didnt tell me anything about it at the time when if he did i would of not cared cause i knew how much we were fighting then and i know he was just being immature about the whole situation.what would you do ? Just drop it and move on?
