HELP!! my 25 y/o H walked out... maybe mlc? HELP!!

[darkestangel]

I went and got a cute haircut today. Very DB!
I've had this gift card to the mall since Xmas, so I went today and shopped a bit.
I started chatting with a guy my age there, and he walked me to my car. He asked me for my number, which I gave him.
He called later, and asked me out, and I said maybe another night. He knows I'm a mom, he knows I'm separated.
Should I go out with him? If only for the sake of getting out of the house and having a few (much needed) laughs?
Or is that just the kiss of death for my marriage?

Part of me thinks, well H is out dating and having sex and whatnot. Me going out on one or two dates isn't that bad. But then another part of me thinks, if I go out with this guy, that's just like sealing the deal on our divorce. And I'm not ready to do that yet.

Any thoughts??
