Endure, because only in that way you two can see some results, whether you continue with your relationship or agree not to.
Once you two have agreed on everything there is to agree about, you can start (not) enjoying the entire process of taking a break from your relationship.
Do this in order to avoid the uncomfortable Ross-and-Rachel situations (you know, ‘but we were on a break’ excuses).
So, together bring the decision on whether you should sleep with other people during your break.
Do what you like doing, turn to your hobbies, start practicing yoga, work on yourself, and improve yourself.
Don’t lock yourself in your room wearing PJs and eating kilograms of chocolate, while watching reruns of every TV show there is. On the contrary, it will just help you feel more and more unhappy.
In order to closely follow what happens with your emotions during that period, you can start writing a diary (if you already aren’t doing so).
But the thing is, there are some things you can do to make the entire situation more bearable.
First of all, in order to avoid uncomfortable misunderstandings, set some rules about your behavior during the brake.
Some couples who find themselves very uncomfortable with taking breaks in a relationship agree on seeing each other once a week or once in a fortnight.
In that way, they still don’t lose the feeling of being in a relationship, stay in touch, and still have enough time to think about the problems in their relationship.
