...It's Getting Hard to Hide...

I recently got separated from my wife after years of marriage. I'm a first-year law student now, and I thought this new chapter would mean focusing solely on my career and rebuilding myself as a single person. But there's this dark thing that's been creeping up on me lately, fantasies about other women, stranger pickup spots, random encounters... My mind races at the most inappropriate times. Tonight, for instance, I went to a bar downtown and ended up texting with someone way out of my comfort zone, a much younger woman. We met in an alley behind the club, her short skirt barely covering what I wanted so badly between those legs... I'm so conflicted because it's not like I want something casual, I think I need more, something deeper than just sex. But as a divorcee in my late twenties, with a professional future ahead of me, I feel utterly lost and ashamed... Is this normal? What should I do? Am I still healing from the divorce or am I just looking for trouble?...
