A passionate "I miss you" message, tweet, or text to your ex soon after may give an opportunity to communicate your actual thoughts to him/her. If you still want to see her/him, tell him/her how much you adore and miss him/her! Let's send a miss you note to your ex for providing you the opportunity to return and rekindle the relationship. If you want to stay cool about it, you can also block your ex on Twitter. This way, he/she will never be able to follow you or send you a direct message.
