It sucks. I know it does.
Whether you saw it coming or you were completely blindsided, it still hurts just the same. Having the person you love turn away from you is one of the worst feelings you can experience. You are left alone, contemplating what you could have done differently. Pretty much everything in the world reminds you of your ex, whether it be a song that comes on the radio, driving past a park that you two used to go to, or even just eating Taco Bell because that was something you guys did together. Then, just when you start to feel okay, the pain returns like the flip of a switch.
I'm here to tell you that it gets better.
When you are at this fragile state, freshly brokenhearted, it is important to let yourself feel all of your emotions: sadness, anger, frustration or anything else you may be feeling. If you try to ignore these emotions then they will build up and cause issues in the future, so get a tub of ice cream, lock yourself in your room and binge watch "Grey's Anatomy" for a couple of days. At the end of those couple of days though, you have to make a decision. You have two options: stay in this stage of sadness and regret, or get back up and start making progress again. The problem with the first option is that you will never heal or improve yourself. The world will keep moving forward and you will be left behind, so I recommend the latter.
First of all, you need to make sure that you like yourself. Maybe your ex had a good reason to break up with you and you know it. Maybe you hate that aspect about you, yourself. Stop blaming yourself, but also stop playing the victim role. Instead, learn from your experience and fix the problem. Work on yourself until you are happy with who you are. At this point, if your ex still doesn't want to give you a chance, then it is time to move on. It is not worth your time to try and prove to someone that you are great. You know that you are great and that is enough; it's their loss if they don't see that.
I need to clarify now, because I do not want you to misinterpret what I said. When I said that it is time to move on, I am not telling you to go and get yourself a rebound or look for a new relationship right away. When I say its time to move on, what I mean is that it is time to focus on yourself. Chances are, you made a lot of sacrifices when you were in a relationship; you probably gave up some of your hobbies, lost sleep or stopped talking to your other friends as much. Its time to get all of that and more back.
You should use all you have regained to improve yourself and accomplish your goals. Just make sure that when you do all of this, you are doing it for you, not because you think it will get your ex back or get you some other future relationship. Improve yourself for you, so that you can be happy and confident in yourself and not care what other people think about you. At this point you should feel no regret about your past relationship, because who you were then does not affect who you are today or who you will be tomorrow.
Finally, through all of this you need to trust in God. Trust that He has a plan for you. He will put people into your life and take people out and that is just how it is. It is all part of the plan. Put your faith in God and He will navigate you through life and keep you right where you need to be. Right now you may not see how your life could possibly be any better without your ex, but eventually it will all make sense and in the mean time you just have to have faith. You have to stay strong and keep moving forward through the pain. Conquer your obstacles and become limitless.
Now its time to take action. Go and show the world what you are made of!
