Move On.
It seems like impossible but you'll get over it. At some point, after giving it your all for the longest time, you'll get tired of struggling to get someone or someone back or whatnot. But the good news is, you'll realize that one day, you're just wasting your time over that someone who doesn't even give a dang or dang anymore. It may seem unfair that they don't give us their time and stuff but thinking about it, we're actually being unfair mostly to ourselves for denying ourselves the happiness and the freedom to enjoy life. But that's another story. At some point in your life, you will feel alone. THAT'S PROBABLY TRUE. But that doesn't mean you are! You just have to re-establish your thinking. Like, don't think that you'll be with that person you want to be with and you'll notice that there are a lot more out there. I'm not saying that you should get them all and stuff but the point is, stop trying to get someon...
