Men are regularly blindsided when their girlfriend breaks up with them, which inevitably leads to the common mistakes that cause her to stray farther away, and possibly abandon hope for the relationship forever. The cause of this is the irrationality men have when they are suddenly left by the woman they love. Desperate attempts to get an ex back in fact have the opposite of the desired effect. These are rules to follow when trying to get your ex back.
1. The most common mistake men make is excessive calling. You may have a lot to say, but she is not ready to listen. It doesn’t matter what you have to say. If you call her continuously she may even have her number changed. Today many people communicate small things through text messaging. This can be an advantage, or complete failure to get an ex back. Use this method wisely! Use it to relay important information, or simply portray your still thinking of her after the breakup. Do NOT say you’re sorry. Start off by texting her something similar to “I hope you are doing well, and just remember that I am here for you if you need anything.”
Seek out situations that can instigate a reply from her. For instance, if her grandmother is sick, use, “I hope you are doing OK. I know your grandmother was sick, is she doing any better? Just know that I am here if you need anything.” Do not attempt to contact her more than twice on any day. You don’t want her to think you’re constantly thinking about her. This will defeat any possibility that you had to get your ex back.
2. This is geared toward men who want to get an ex back, and have the advantage of being active in the same social circle as their ex. Attending a gathering of friends is the best, or the worst thing you can do when trying to get an ex back. It is a situation that must be used delicately. Obviously, leave her be. Do not follow her around, in fact, other than a glance and a casual “hello”, do not attempt to make conversation with her.
Instead, show her that you’re OK and are the same person around your friends with or without her. Yes, in truth it does do some good to converse with other girls, which naturally triggers a jealous feeling, but the biggest mistake made is by flirting with other girls. This is seen as uncalled for, and an intentional attempt to hurt her which will probably eliminate any chance you had to get your ex back. Be casual, but portray you’re having fun by laughing and making jokes, as this will gravitate her to you.
Now you know the two things every guy must know when trying to get an ex back. What you do aside from this will need to be just as well thought out and planned, no tricks will work if your ex has even a remote amount of intelligence.
