It’s responsible, polite and keeps your calendar orderly.
You are by no way bound by a list of “rules” as to how many days to wait to call, or any nonsense about how the man should always call first.
It not only keeps your feed full of things you want to read, it also sends a clear message that you are truly leaving, which is the most important aspect.*DISCLAIMER: This is not an excuse to call constantly.
If you have something of value to say, a question to ask or plans to confirm, then do so.
Give him that space; don’t pepper him with questions and ultimatums with the hope that he will simply bend to what you’ve decided a relationship means. You get to enjoy the same space you’ve offered him. Make REAL space by doing your own thing, hanging with friends and giving thought to the type of relationship you would like to have, whether it's with him, or not.
NEWSFLASH: Losing him may be the best thing that’s ever happened to you, or in the very least, if you two find you cannot live without each other, he will come crawling back with more respect, devotion and perspective than ever before.
This is the time to delete his number, or save it under something like, “DON’T,” and do not text, call, send smoke signals or message him on any social media.
You made a choice to leave the relationship, and it’s important you remember why you decided this.
Ask what’s going on, or why he’s been distant and listen to the answer, taking real cues from what he says. Suggest a fun date night, or weekend away to get his mind off things.
If he can’t give you a direct answer, his distance may be directly related to you and doubts he’s having about you two getting close. If anything, he’s just being cautious or needs some space to see what’s next for him in this union.
Take it at face value and make moves from your heart.
