If there is one mistake that guys make when they want their ex back is they intentionally show her that they cannot live without her. This is one thing that you should not do on “how to get my ex girlfriend back”—don’t show to her that you cannot live without her because she won’t pity you. She might even drift away from you more. Instead, so the opposite: fix yourself, act happy (even if you’re not), show her that you’re taking of yourself without her and pretend that you’re moving on. Show her that you are enjoying your life without her and you’ll see that she’ll be calling you to see how you are doing.
