Hey, i feel your pain. Honestly, I had an ex that treated me well, lied about everything and pretended to love me for 2 years. She cheated on me pretty much the whole time. I'm feeling like "what did i do to deserve this". I'm just as alone as you are right now, except im 22 and am just being a huge baby, but man, this hurts. It hurts, no matter what you do. What I have heard, is live your life, keep a positive mental attitude, keep your head up, walk tall, love yourself and everything will fall into place. It's been helping me alot. Stay strong
