My 4 cents (inflation)...

Go out with your friend. If your friend bails out on you, go out anyway. Roll in late and see what he says. I did this a few times during the last 2 weeks that my W was in the house and it seemed like it affected her. She began asking questions about what I was doing, where I was going etc. At one point she said (in kind of a pissy mood), "Do you have a hot date or something?"

Also it was during that time that she came to me out of the blue with an apology for all she's put me through and asked me if she could start seeing our MFT again. She has gone once and has a 2nd appointment next week (my next appt w/MFT is Monday). She still moved out and she's still hot(ter) and heavy(er) with the OP but obviously something different is rattling around in her cranium.

JV, go out! Have fun!
