It is tough being a stud muffin. Your new attitude toward life, way of approaching things is very appealing. Attention, especially from the opposite sex, is very electrifying.
Your only question is.. do you want the marriage? What do you want for your children?
The attention, pursuit, flirting are all ego boosts which end up leading you back to the same place... what do you want out of a relationship? You can date, tease, boink all the beauties but what is your end goal?
That's what so tough.. what do you want in the end?
Things changed for me when I was begging him for money for the kids. Parents look out for their children. It's hard to respect someone who doesn't.
