After your relationship has broken you may feel that what ever happened was not good and making attempt to make your ex return your phone call but your ex is not responding or returning your calls which may be little annoying for you...
You just need to take a break.
Even after so many calls you have been making, if your e does not respond back then the best thing is to leave him alone for some time.
The more you keep calling it is likely for you ex to go away.
Just give a break.
Never try to call from a common phone or unidentified number.
That will irritate him further.
You need to maintain silence which will ignite the curiosity in your ex as to why you are not responding.
This will at times make your Ex return your phone calls to you.
He may wonder whether you have left the town or entered a relationship with some one else etc.
Give your ex a break and call him/her again after few weeks.
May be you will get a response or answer to your call.
It is but natural for your ex to be anxious about you, as long as you kept calling and once they do not hear from you something will be burning from the bottom of his heart.
You need to be very patient and wait for his call rather than nagging too much.
After a break call him/her again and enquire what he is doing these days.
It may make things better.
After this formal call give him another break before you call your ex again.
This may not be irritating.
If you display a casual attitude then it will make your ex wonder if you have really broken off the old relationship for ever.
Now your ex may want to meet you.
