Lets face it, we have all been in, or at some point will be in, a relationship where we find ourselves clinging to someone who really doesn't deserve us. So how do you escape?
Well, unfortunately it takes time, and lots of it! The best way to get back on your feet is to find something that makes you happy. Not something like sitting around and watching your favorite t.v. show, because it makes you laugh, but something that triggers your passion. It should be something that takes up time in your life and while your doing it you don't even think about that "person". The more you throw yourself into something that makes you happy, the more you are proving to yourself that you don't need to be stuck in a relationship that doesn't make you feel the exact same way. If you can go out and do things independently then why do you think you need to be so codependent in a relationship? A huge factor in breaking free is letting that "person" see that you are slowly disassociating yourself. There is nothing worse than blind siding someone with a break-up no matter what the relationship is like. They will probably try to win you back by saying all the right things, but do NOT get caught up in it all again. We all know they can say anything in the moment, but as soon as you show a little interest again its back to the same old problems you had before. Surround yourself with positivity and lots of laughs. Soon you will notice that while your out having fun and they are blowing up your phone trying to apologize that it doesn't even matter to you and you no longer would rather spend your time trying to argue and figure things out when you could be enjoying yourself. Finally you are finding your indepedence again! The most important step in all this is to take your time with your happiness. You don't want to find all this bliss and indepedence and then jump right back into a new relationship that can pull you back down. You need time for yourself.
