Move on and don't feel sorry for yourself, you must embrace change. How can you expect things to get better if there is no change. Control your mind, only focus on things you can change, don't have engrossing thoughts on things you simply can't control. In life sometimes you have to be done, for your wellbeing. Done putting in effort where it's not reciprocated, done fighting for someone who doesn't fight for you, done trying to prove to someone you are right for them… just done. All of us who have been through heartbreak know its fucking hard but you know it has to be this way for you. Stop thinking about what will happen in a few months or even a year and start focusing on the present. The glorious present will get you to where you are meant to be, the healing and growth everyday will lead you to places you can't imagine right now. So focus on everyday and what you want to achieve by the end of that day. Closure and change will only come forward when you accept letting go is more beneficial for you, knowing in your heart and soul that where you are right now is all in place for a reason. You will feel this change taking place when you stop living in the past, yes have memories but look at them in happiness. Don't dwell on the fact that they are over but be grateful that they happened. These memories helped shape you today, the past relationship built a part of you that you needed to experience, it's all happened for a reason. You will learn to be okay with change and losing people, if they are meant to be in your life you will find yourselves again. No one can say they will come back, it's all up in the air, let fate run its course and believe in yourself. Remember, don't let the idea of a relationship tarnish your precious mind, give everything time.
