One rule is well agreed upon by everyone when it comes to matters of getting your ex back after a breakup, and that is called the no contact rule and involves breaking all kind of ties with you ex.
However hostile it may sound about getting your ex back, the surprising part of that is that it works! You need to realize that when you are no longer in contact with you ex you are actually giving your ex space and of course the time to get healed and it would not be long that your ex starts missing you.
Your ex's curiosity is kindled by your act of disappearing; they would seek to know where you have been.
This is the nature of being human.
That said you also need to be wary of the fact that there are instances when the no contact rule would no longer apply and needs relaxation, these being exceptions to the rule.
Ties with the family It would be insensitive in not letting your ex know the things that are happening with your family, this is if you and your ex had spent time between one another's families.
Keeping your ex away from any big news in your family by your disappearance act would not be the best of the ways in getting back with your ex; hence, an exception needs to be made to the rule of no contact in the midst of a family emergency or some important happening.
Continue with the communication Incommunicado again would not apply in a situation where the pain and hurt created needs a vent, it may be necessary to sort out things through talking between yourselves, else, the chance of getting your ex back would be a bleak.
And when you ex calls It is weeks together since you have done the disappearing act and during this period you have not responded to you ex's calls or had bothered to reply to your ex's emails.
You need not ignore any of them hereon.
After a good phase of the no contact rule, now you need to replace it with the reach out rule.
Get to your ex and get noticed.
