Most Helpful Girl
It seems you are this Fickle Pickle, @RoyalBlue87, who Loves Two girls, One in which 'There is nothing wrong about her or our relationship.' You just Want perhaps something that is new, and knowing you cannot have your cake and Eat it Two... Now want to break up with her...
The grass is Not always greener on the other side of the fence here, dear, just a little something I thought I might throw your way today. You may Think you are In Love with the Other newbie calf, but on your SO Behalf, you may find out that what you have at home isn't all bad and that you are Missing the Kissing... Someday.
It Will be Most Damaging, no doubt about it. And if you mess it up by tearing down the Very Foundation that you both have built, should something go wrong in the so-called 'Greener pasture,' she will Never trust you again nor Believe Nor You... Until the cows come home.
Do some serious soul searching before you leap into those murky waters that may lead you to No looking back with a new Quack that just may go dead someday.
If Anything, take a Break from your Current and tell her you want to find yourself and take some time and space to see if there is More in store, but don't Commit to this chick at hand at the Moment... You just may ending up breaking her heart with this nest you are trying to make with a New Take you are unfamiliar with.
Good luck. xx
