Relationship insight? help!?

my gf and i relationship lately hasnt been going so well.. weve been having some troubles, she wanted a lil space for herself, so we both tlked and eventually agreed to a break from being all lovey dovey, we are still in a relationship and in no way are either of us talking to other people.. its not like that at all.. its been hard though becuz we have been talking alot veryday like normal, so i feel as if im smoothering her.. its been emotionally hard for me to control my emotions th past few days and thats not gonna help us... she wants to do her own thing for a bit but also doesnt want us to breakup.. iknow she is trying and i am also.. so we mentioned that maybe a break for several weeks or a period.of time with no contact.. so itll give her time and me time also, we will set time apart and set a date to meet up and really deeply communicate. we are still in a relationship and neither of us wants it to end. what are your thoughts, opinions, how much time should we allow and what should be the details? hav you been in a similar situation? ladies and gents please help! *we are in our mid twenties, not some highschool fling and have been in a dedicated relationship for two years.
