Ultimately, no one else is in your relationship and every relationship is different. I know I keep some things from my family and friends about my husbands behavior because they would judge him and that is not their place when he has mental health episodes.
You know your partner better than anyone, and if you don't to me that's a red flag all of its own. Why do you think he needed the break? What has he been doing on the break? I agree with what other have said, it is very rare for a man to leave his current partner to be single. I know men who have been dumped and have a new partner in weeks and all the other who left had someone else in the wings. Men are generally lazy and why would they leave to be on their own unless they had something else lined up. Also, I find that most men spend so long in their heads by the time they have spoke to you about the issues the relationship is over and has been for a while in their minds.
I hope it all works out for you, but be prepared it may not have the outcome you want. Take some time to focus on you, your life and what you want rather than waiting for him to decide if he want to be in it with you.
