Jan, as others have suggested, employ this 30 day no contact rule if it’s what’s best for YOU and your heart. I think if you do it in an effort to “win him back”, you are setting yourself up for disappointment. Not because he won’t come back (he might, or he might not), but because you are leaving your happiness and well-being in his hands. I would recommend you use this time apart from him to consider your own needs. What do you want in a relationship, in a partner? What value do you add to a relationship? What makes you happy? You are a valuable, loving person with much to offer. Whether or not this guy sees it does not increase or diminish that value in any way. Take loving care of you.
