The result most desire from the take-a-break concept is that the one who needed the break realizes that they miss the other and finds that life is not the same without the other in their life. That naturally causes certitude of the heart and a peace about getting back together and getting more serious.
Love between a man and woman should produce great clarity about the direction of their relationship and their lives. Just because we have fears doesn’t mean there is not love. Too often great relationships are wounded or broken due to the inability of one or both to get past their own self-imposed issues.
What really happens is they are afraid of love. Love demands and requires everything. Giving up anything, for some people, is too unreasonable or difficult. Thus, the relationship stagnates because one or both cannot keep letting go of selfishness.
I’m concerned that you mentioned the need to discern God’s will in this. I am all for God’s will, but too often I hear single people use God as an excuse for what is the real reason for their situation; namely, their own fears or indecision. God loves decision-makers, and He is always waiting to bless couples as they make commitment moves in their relationships.
At each stage of a relationship, it is the two individuals making decision. God is there to bless them and provide graces to strengthen the path. To stop the process and say “I have to discern” can too often be an easy cop out for our own inabilities to proceed. It’s not God at all who has anything to do with it.
Be careful about over discerning. God is always where peace is consistently. I often tell people that the devil shakes in the moment, and God holds us over time. Meaning, we make bad decisions when we are in the middle of unrest and chaos of situations, events and emotions. God lays peace on our hearts over time.
