You must be going through a phase wherein you are trying very hard to get your ex back into your life but he/she does not seem to be interested and is in fact ignoring and avoiding you.
Well, if this is the case than there is no need to be depressed as the following ways can help you get your ex back even if he/she is avoiding you big time.
Way 1 There might be high chances that your ex would not reply to your phone calls and not pay any attention to your text messages.
You should try putting your feelings in the form of words and convey it to him/her in the form of a letter.
This formula usually works as your ex might find it very difficult to ignore the letter and might end up reading it.
Way 2 In case your ex is not answering your phone calls than a short text message can help you in a long way.
However, make sure that you do not type anything about your relationship.
Instead, say hi or simply give regards and best wishes for the day.
Way 3 If the above two are not working than you can even try using some more technology.
There is no harm in sending a small video clip or even dedicating a song to your ex.
A video is probably something that your ex would not expect and hence he/she would really respect the fact that you are taking so many efforts.
Way 4 Invite all your friends for a surprise party or ask one of your common friends to arrange a party and invite your ex as well.
This way you would get to meet your ex and try and sort out things.
