Ouch.
It's never easy to win back an ex girlfriend, but when she hates you too? That's a tough situation.
Here are some tips to help you win her back.
Figure out where you messed up.
OK, she hates you. But why? Figure out which of your actions made her so angry.
(Disclaimer: they should be legitimate reasons. Otherwise you may be trying to get back with a woman who isn't good for you! For example, flirting with other girls all the time? Good reason for her to be angry. Mad about eating your food too slowly? Stay away from her!)
(Second disclaimer: If things ended because you were a jerk, think carefully about whether it's fair to loop her back in.)
Start changing your behavior for real.
Girls can usually tell when you're putting on an act. If you want to change for the better so that you can get your ex girlfriend back, you need to change for real. Do it for you, away from her.
For example, if she grew concerned that you weren't motivated enough to be her partner because you had just been fired from your job and were partying every day, start motivating yourself! Get your actions in order. Become the motivated man she aspired for you to be.
(Disclaimer: you must also want to be that kind of man, but perhaps hadn't in the past out for whatever reason. Don't become someone you're not; be the better version of yourself you aspire to be. If she's good for you, chances are she wants the same thing for you.)
Take your time.
It's usually not idea to hop in and out of relationships, but it's even more rocky if one partner has deep emotional baggage about their partner. Take your time with rekindling your romance! Even if she shows hints that she may want to get back together, resist the urge to dive in. It could backfire.
Don't promote jealousy.
Some men try to flaunt their conquests in front of the woman they want to be with, as though they're trying to say: Look how desirable I am!
For some women, this may work, but think about it: you would only attract the type of woman who wants what she can't have, not what she really wants. To start things on healthier footing, keep jealousy out of the mix. Feel free to date (you're single!), but don't rub it in your ex's face, thinking it will inspire her to run back into your arms. Probably won't work, and will only make things worse.
Know when you're defeated.
She may want nothing to do with you. At least not for a long, long time. If that seems to be the case, don't drag it out. Resist investing loads of emotional energy into a partnership that isn't to be.
Besides, if you keep going after her, you could completely obliterate your chances of getting back with her some time in the distant future.
Relationships are complicated, and ending them is even worse. Sometimes men realize what they had after that person is gone, forcing them to frantically wonder: How can I get my ex girlfriend back?!
A good mentality to have when trying to win an ex back, especially if she seems to hate your guts, if the idea that you're making life improvements for you and if she doesn't return, it will be difficult, but you will be able to find someone else.
