Well, I'm in my mid-thirties. Earlier this year, I discovered that my wife was having an affair with one of my friends (and her friend's husband). Long story short, that is still going on, and they are deciding upon their future, should he leave his wife and child. What fun! And also great for my ego!
I did everything I could to save the marriage, but at a certain point, I knew it was over. Definitely the most painful thing I have ever been thrugh emotionally. At a certain point, though, you let go of everything. And I have decided to sow my wild oats, so to speak.
The biggest thing I'd have to tell you guys is that there is no need for lying and deception. I have been amazed at when I tell a woman (who just one drink prior was looking for a LTR) that I am not looking for a relationship-how cool they are with pursuing a short-term physical thing.
I have attacked this beast with a three-pronged attack. First I still meet women in my daily life. Second, my friends want to get me laid more than I do myself (in some cases). Finally, I put together an online profile. I have been on dates with more women in 3 weeks, than in the 2 years prior to meeting my wife. I go into these dates not giving a flying eff. And it works, somehow. I've had similar talks with my (same age) friends who have been through the marriage grinder. It is amazing how much easier it is now, than when we younger. Just remember, women want it as much as we do-especially as they get into their late thirties and forties. If you are honest, (and awesome in your own way)you don't have to be "relationship guy" to get some.
