During your relationship, when things went awry, you played on your ex's emotions to win your argument. Nine times out of ten your ex felt so much pity for you that he / she relented, and you got what you wanted. However, now that your relationship has ended, do not try using this tactic to get your ex back – it just WON "T work!
What you call arguments that you had during your relationship were nothing but little tiffs. If you burnt the food and did not feel like making more and wanted take-out, you pleaded tiredness, and your ex everave in – you got your takeout. You decided to go out an rent a movie, but you each wanted different movies, you pouted and gave your ex silent treatment for a while, and in the end you won and your ex had to suffer through the movie that you wanted to watch .
These are not arguments – they are tiny discrepancies that are so trivial, that they are not even worth mentioning. What happened at the time of your break up though, is a totally different story. The argument started out about something quite important to both of you. Neither of you would give in so the argument escalated out of control.
You ended up screaming obscenities at each other and saying the most terrible things to each other as well. Still neither of you would give in. Then things got so out of hand and ugly, that your ex walked out on you. To get your ex back is going to take a whole lot more than a little pity – it all depends on whether you love each other other enough if you will be able to get back together again.
You have to accept that the relationship is over, and, if you really love your ex, be prepared to start all over again. Before you can do that though, you have to change quite a few things about yourself. You must accept that relationships are supposed to be fifty / fifty, and be prepared to work hard at your half of the responsibilities.
To get your ex back you will have to convince him / her about your willingness to do your bit as long as you can be together. Maybe you can get your ex to love you as much as before and think about getting back together again.
