Okay people,cool off a little bit.
For the bitter ones...
PEOPLE DO CHANGE.
CHANGE IS A PROCESS.
If YOU, as his or her lover want and learn how to support your partner's change, you WILL see miracles.
When all of you above say people never change, I wonder how often have you really supported them to change. I don't say it is easy. I just say SOMETIMES IT'S WORTH IT !!!
Now dear "romantic"..you and him share a great connection. It is normal that you don't understand why he still wants to keep his skills. I don't either.
But perhaps this IS a part of him; a playful and macho part of him. He will not let it go just because you ask him to.
You actually have two options here:
1) The playful way - what if you would go out with him when he wants to pickup other girls...what if you would also innocently flirt with other guys? What if you would point to him hey...that's a hot one...go scare her, tiger...
He will be shocked, I guarantee you. The only problem is if YOU could stand this thing...and I FEEL that you wouldn't. So here's your second option:
2) The deep way - this way is harder, as it goes for his letting go of this "macho" part of him. As I said, you won't do it just asking him to stop or change...eventually you should end up telling him how much it hurts you and if he loves you he should ask for your help to stop doing this thing.
Of course you can mix both options
Best wishes!
