I got out of a long-term relationship a year ago.
Jackson, well I guess you could look at this as a learning experience:
It sounds to me like you were pretty lukewarm about the relationship anyway, that he's the one who moved it along. It still doesn't make lying OK, of course. I am 57, and trust me, age does not always translate to wisdom and maturity in men or women.
Perhaps he is the type of guy who can never be without a relationship, and you were actually his "better than nothing until someone else comes along." Yes, I know he's been telling you "it's only you" but I think that's just some mens' MO.
Normally I would say take the high road, but I think in this case you can confront him, tell him about your friend, etc. It might just set him straight for the future, but perhaps not. You don't need to tell him that your friend created the profile to entrap him.
And it goes without saying, dump him.
I am going to dump him.
He sounds like a complete idiot. I'm glad you dumped him and moved on. Not all men are like that.
I'm sorry this happened to you. You need to dump him for sure. Many men are very stupid and don't know a good thing when they have it. Just a guess here but maybe after being in a R/S with you he realized you were incompatible in some ways and was trying to see if he could find something else but didn't have the courage to let you go before he has a new person. You can try to find out what's changed for your satisfaction but in the end, you don't want to be with someone who no longer want to be with you.
