Dear Nina:

I think that it’s a good  choice on your part to not call him, so to not “interrupt him with his space”. It is considerate of you to give him the space “he needs right now”.

If and when he contacts you, make sure that fighting will never be a part of your interactions with him. Fighting really is not necessary, and as you can see, often both parties to the fight lose.

Key sentence to your question (“Is there still hope?”) is this: “He told me that he is 100% sure about his decision, but also said that if he would regret he would tell me”-

– “100% sure” is a high percentage suggesting no hope for the relationship, but people change their minds, depending on circumstances and their own behavioral history. Do you know him (from before the breakup)  to be sure of things, and then change his mind?
