I see it so often! Both here and IRL, I am seriously starting to think that 90% of people are fucked up the head.
Why waste time on something that will obviously never work? For example, exes. I can't understand how someone can go back to their ex and act like a breakup never happened. It happened! And for a reason. That main and sole reason that brought you together doesn't exist anymore after the breakup. One of you doesn't feel the same anymore and that is THE END. Game over. Those same feelings you or them had in the beginning do not exist anymore, there are only some traces of it and some new feelings. How can people just pretend that this is not true and repeatedly go back trying to fix it? It's beating the dead horse. I could never go back to someone who's feelings for me changed. Who's not on the same page as me. I can still respect them and care about them, but the relationship is O.V.E.R. Trying to fix it just prolongs the misery. It goes against all meaning of love. Going back to an ex is like spitting in the face of love, it shames its meaning. Going back to an ex means you completely gave up on love, and most importantly, on your own value. It shows that you have such a low opinion of yourself, that you are desperate and incapable of finding a new love. How can that make you happy?
Same goes for people chasing after people who obviously don't see them that way. Let me give you some advice...
Ladies: Stop wondering and over-analyzing if a guy likes you! If he does he will show you and tell you, he will freaking do something and you will know. If you don't know, then he doesn't like you. It's as simple as that. If he really likes you, you will never, ever doubt it. Not even for a second. It will just feel right and you will be making out instead of posting here. So do yourself a favor and go live a simple life and do something productive, because the right guy will show up eventually. Whining about it won't teleport him to you.
Gentleman: Same as for ladies, stop wasting your time and energy on women that don't like you. Pay closer attention to your surroundings and approach girls that you find kind and have things in common. The right girl will show up and she will be more then obvious about you. You will know. She won't be confusing, she won't lead you on, she will be the easiest catch ever (for you). Easy is good. There is no such thing as playing hard to get! If she's hard to get or hard to keep then she's not the one. MOVE ON.
I know rejection sucks. I know being led on sucks even more. But what you don't know is that you can avoid it, by being smarter. Never change for anyone. You want someone who will want you just the way you are. Because what someone doesn't see in you is what they will never be. And someone is going to see you eventually. Keep going and remember that every time someone rejects you or fools you, you are just one step closer to finding the right one. And when you do, it will be the best damn feeling in the world. You will be so freaking glad that all those people before rejected you.
