<human>: Give me the gist of the text in a nutshell

My fiance is at work right now. We've been together 4 years. When I got home, I found a piece of paper where his car normally parks, as if it fell out of his car or his things. We live together (alone) and no one else has used our driveway recently.

The note looks like it was written by a girl and reads "If you would be willing to talk at some point. I really really miss you but I don't know if I can try to make anything better w/o talking with you & trying to work sh*t out. I'm thinking all the time about this & I know you thought it wouldn't be a big deal for me but it is, constantly."

It appears to be on the back of a transfer slip from a regional bank. The only identifying thing that I found was a toll-free number for the bank. After some web searches, I found that this bank only has a few branches. Most are in a neighboring state (a state that we both lived in a year ago). There is also a branch near where my fiance went to college (about 1.5 hours from where we live now).

I honestly NEVER thought that he would cheat on me, but this note is super suspicious.

He comes home in a few hours. What should I do?! If he is cheating, won't he just deny it anyway?
<bot>: Found a note in the driveway where my fiance's car is parked that sounds like it was written by another woman.  What should I do?
