Well..... You can start changing by a) not interacting with women significantly younger than you and b) when you do talk to a younger woman remember that she is viewing you as an older parent and will not be viewing you as a potential sexual partner so they are NOT flirting with you. And c) take people's advice and join a dating site.

You make the choice to interact with girls - and you've never mentioned in any of your threads anything about women even approaching your age bracket. It's not that you are doomed - you throw yourself into the fire and are surprised when it burns you.

Until you accept the fact that it is a choice you make... It will never get better. You have to take ownership over your actions and choices. You choose to fixate on young women. You choose to entertain the illusion that they are flirting with you. You choose to not make your intentions clear with them. You choose to not take advice on how to meet women who may view you as a potential mate.

It isn't that you are losing battles. You just choose to go to a race track dressed in football gear - you keep choosing to go to the wrong stadium. That's not losing a battle, it's not even attending the battle and being upset when the others don't stop and join your game.
