Hi Noemi,
Yes, as of now, you shouldn’t initiate contact. That includes texting and snaps.
Even though he may be slowly opening up your old snaps, you shouldn’t initiate a random snap here and there.
Yes, you should completely disappear and give him space.
This is a strategy of making yourself a lot less available to him.
Something that is scarcely available tends to have more value than something that is readily available all the time.
Focus on your life for now and leave him be.
This is often one of the most effective ways to make a guy start seeing your value and consequently try to save a relationship.
