If You Love Something, Let It Go

My opinion of the whole '3 weeks' separation: I agree it may help him out on becoming a better man for himself, but I don't know how it will affect us in a relationship. Its poetic when someone recites "if you love something let it go, if it comes back to you, then its yours" but it's not reality because your playing with someone's emotions thinking to let a relationship go to see if it will be the same or become better. It's a game when a person does that. Right?

Separation from the Relationship

So he wants to take a break for several weeks from the relationship to get himself together?
But what does he have to do in several weeks that he can't do sooner and work at it together??? After just finding out on Valentines Day of this year his ex-girlfriend keeps calling him, even though she somehow got a hold of his new number he claims he didn't give her, he hasn't told her he has a girlfriend for the past 11 months! I just don't understand how he would get on my case for talking to my friend (though he is also my ex from +5 years ago) who knows i am in a relationship from the beginning and he is also in his own relationship, that my boyfriend couldn't even tell his ex he was in a relationship. Next month will be our 1 year anniversary.
So now he wants 3 weeks to get himself together to be the man he wants/needs to be for himself and for me.
What am I to think?!
