Hi, sorry you got here but you will get great help. We all do/did!
How did you respond to what he said? He has admitted being in an EA and that means that his mind is somewhere else.
At this point you cant control what he does, if he will meet that person or not or what he is thinking. You can only control yourself and your goal would be to make yourself "attractive" again. A baby usually takes a toll on us women, we neglect ourselves, our priorities change and that many times causes the couple to drift apart. Can you tell us a bit more about your sitch? How old are you, howl ong you've been together, are you working, your relationship dynamics, any other changes in his behavior, etc etc... Dont be shy, the more info you feel comfortable giving, the better people can help by giving you their thoughts.
Read some threads here, try and find the advice to newcomers, when you feel comfortable enough post to some people you feel their sitch is similar to yours or you feel you can relate.
Take it slow and try to be calm. I know it sucks, I've been there but believe me, you can deal with it. Good luck K
