I think varied experience is good, it broadens horizons and builds understanding of what's out there.
But personally I believe in if it's not broken don't fix it when it comes to relationship. I wouldn't give up on a relationship if everything was good just because I'm curious. The guilt would kill me.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
