This just sucks

We talked some last night. Then today I remembered, once before I found info. from a dating site in our email. This makes me wonder, is this something he's been doing all along. He swears that talking is all he's done, but isn't that enough? At some point would it have progressed to more than that? Isn't that how is starts? I just don't understand it. I'm not so sure I want to. Right now I'm pissed off and hurt. Monday we are going together to talk with his therapist. I'm hoping that it will help.
