I found out the guy I'm dating has a dating profile on plentyoffish.com. We just started dating again about a month ago. Back in the summer after dating him on and off for a year, he fully cheated on me and had another girl on the side and I found out about it. Obviously I broke up with him right away, and he's spent the past few months fighting to get me back. I still had such strong feelings for him and it was really hard for me when he was saying all the right things, and as scared as I was, I let him back in.
Anyways, we both got new macbooks recently, and I've had a mac before so I was setting his preferences for him on safarai (internet browser). There's this area for setting the sites for 'auto fill', which are all the sites like google, facebook, amazon, etc where you enter a login name or do a search. Since his computer is brand new there are only a few sites on it including facebook, hotmail, and….plentyoffish. I checked his internet history, and he had deleted it. I didn't want to freak out right away just in case I was taking it the wrong way, maybe a friend was using his computer or he had gone to that site by accident. So I decided to look at the profiles for guys where he lives in his age group, and although he doesn't have a pic up, his profile is SO PREDICTABLE. As soon as I read it, I was 100% sure it was him. So in my fury I sent up a fake account and I decided to see if I could get him interested in me, and I posed as this blonde bimbo type of girl but I didn't put up any pics. Sure enough….he msged me back. So I asked him to add me to msn (I set up a fake hotmail account and everything), and we chatted on msn WHILE he was talking to the real me. He was totally flirting with my alter ego and told her that he had just gotten out of a long term serious relationship and had bad luck with girls recently, and hadn't found that "special someone yet".
Omg I feel soo sick right now. He even sent me his real pics, one of which was a pic of him and I and he had blacked me out of it. It got so bad that he even emailed this "Katie" chick that I made up while I was sitting right next to him on my own computer. I feel sick, I'm shaking right now. I don't know how to handle this. I know its over, but should I tell him that this "Katie" chick is really me and let him know he's busted, or should I just leave it??
