Here, your newest installment of Ask Lynn, the advice column penned by BG’s alter ego, now appearing on the spanking-new Lifestyle channel at MSN.com (and powered by Match.com). This week, we meet Maybe Not So Mature?, who’s doing a little morning-after quarterbacking after a hot and — well, not that heavy one-night stand.

“I knew this was nothing but a fling,” she laments, noting that he’s four years younger (maybe not a huge mathematical difference, but it gives him a whole different digit in the tens place) and that they have nothing in common except that neither lives in the other’s state. “[But] I cannot stop thinking about him. It’s driving me nuts! This is not what I need because I am finally ready to date after being divorced over a year and dating losers for six months. I feel weak for sitting and hoping that he calls. What should I do?”

Other than be stoked that girlfriend’s still got it? Not a whole lot! See what else Lynn has to say, and then come back here to comment!
