Of the many things I could imagine somene shouting out at the peak of passion, “I’m convinced” is way down on the list.
The nefarious imp in me keeps saying that she really did say “Uncle Vince”, and was covering.
Huh. So my brother’s friend Quasar got married then, hey? (Actually, I doubt this is your guy. But he does have an interesting first name that starts with “Q.” My brother met him in the Air Force. Everyone called him Q. And I can see why.)
So a woman was having an affair with you but got embarrassed when she called you her husband’s name? 
You can’t picture something like:
He: “I’m going to show you things you’ve never seen before.”
She: “Yeah right.”
…
Shee: “I’m convinced”
Possible, but the setup’s too long. And you’d think she would’ve said something about it to allay her lover’s suspicions.
I’m still suspicious.
I’m still waiting for this thread to get into position right over “That killed the mood.” 
First time I made out with the lass who became my wife, for some bizarre reason, I used a name of a girl who I despised, but spent that summer pursuing me. Fortunately, this name happened to also be my wife’s middle name, so there wasn’t too much drama… I just convincingly (I guess - we got married) told her that she didn’t hear me say her first name and only caught the second.
:o
And that worked. Until now.

Damned internet…
