Cake eating or progress?

[Dom R]

He was NOT his friendly self. He was sort of distant. After an hour, he says he is going home. I was pouty and he said "I'm staying over tomorrow night."

He's been bad to you.. he's been caught... and you let HIM control everything?
under YOUR guesswork, he went on a date, 'cause he drove the mustang.
but you're the one feeling guilty?!!

Seems like this is, from his perspective:

"Oh-oh... i've been caught. How bad is this going to be? Can I still control the situation, so she doesnt come down on me? YES! ok, i'm just fine, no problem"

I'm no expert, but it's what I imagine a "Player" would do, to calm down one of his girlfriends.

"you're pissed at me baby? ok i'll stay the night with you tomorrow"

He DID drive the Mustang. I mentioned that, and he said "I bought her to drive her; it's nice out and I love driving her." I think the food thing convinces me that he wasn't out.

arrrggg....

It's falling apart (again) and I don't even really know why. I guess it's easiest for me to say that I pressured him too much by asking what the deal was when we returned home, sighing and now tonight. Simply brilliant. I could just kick myself.

you did NOT do wrong by asking him that, given your situation.
Things are going badly, because HE started looking for/going on a date with someone else.
Why he did THAT, is the root problem here.

Supposedly he will get rid of the match profile; but he is mad I was checking up on him. He is distant.

he is mad he was caught.

I think you have a choice here:

you can stand BACK.... and see how long he goes on a dating binge THIS time..... or you can stand UP... and say "this is it. Show me your match profile, and lets talk about how we should be treating each other. (even if we're "only" exclusively dating)

People have chosen either way for their own marriages before. I think either way has a potential to work for you, and either way has a potential for failure.
You might want to talk to "a professional" at this point if you can.

At some point, you have to have "a big R talk". The DB thing about "never having R talk" has to be taken with a grain of salt.
Now might be a time for that, for you.

Maybe you "catching" him, was enough to stop his sliding down that road. THIS time. But whether you choose the hardnosed approach, or a softer one... sounds like you still could benefit from a talk with him on where things are between you, and what you can expect from each other right now.
