False Hopes and Promises

I find it silly that there are always promises and false hopes at the end of a relationship. EX. Oh we'll always be friends and we'll talk all the time. This never happens ladies and gentlemen. NEVER. I've kept a semi decent relationship with all of my ex's, and as of right now, 50% of them won't ever talk to me again (so they say), and 1 of those 3 i'd like to talk to. The other ones are a waste of my time. I can't help but notice that 20 minutes ago, it was "I'll always be here for you too," and now it's "I can't talk to you anymore, it's the only way I'll ever get over you." Rofl to that.
I hate predicting things like this. I hate just slowly pulling away from someone because you know it's going to end. For once I wish I could just be left. I want a relationship to end like a band aid. I want it to be boom DONE. Not, ah crap, I'm my own worst enemy so this is going to end, better get ready for it.
Let's clear things up right here right now. I cheated once. I don't give a flying monkeys blue butt what every girl thinks, I needed someone and they were there for me and that is that. If you weren't so selfish sometimes, you could have realized that. I didn't tell the truth because the truth gets us where we are today. With you not talking to me. I would have told you, yeah I really would have, but I would have waited to where we could talk about it, not have it be this dumb thing. [Girls, never say you're over something. You aren't. Trust is the most important thing to a relationship. Don't think you can carry on without. I'm not saying things can't be worked out, but don't bury something for it to come up later.] The reason why I'm Ok with this, is because you told me you had feelings for someone, and you CONTINUSLY spent time with him, EVEN after he kissed you. I'm sorry, but fuck that. I can't cuddle, but you can hang out with him all the time? Yeah, that's bull. Our relationship ended when you continued to spend time with him. I still thought we had a chance, I figured once I moved up we'd clear things up, but I was wrong. You let rumors run our relationship, you let people 800 miles away tell you what was going on, people I NEVER SEE or TALK TO. I'll take blame for you losing trust in me, but you ruined our relationship. You never came to me when you heard something, you went to someone else. Screw that. You ended this. You can ask anyone, you can tell them the story and the might say it's my fault, but I know. Cause it's not like I sat around waiting for you, finding ways to kill time. I almost sacrificed everything for you, and I was would have in a heart beat. I would have given everything I had to you. Even though no one had faith in us. I believed. I never doubted. But forget that.
I didn't say this to you because I don't want to argue. It's not worth either our emotion or time. But I'm putting it down on this, cause whether or not you read it, I needed to get it off my chest. I've been mentally aware this would happen, but emotionally I'm in a state of shock still. At the end of the day, how things progress is completely up to you. I'm offering you the same thing I did all the others. I'm still here as your best friend, because that's what I was before we took this to the next level. If you don't want me as that, that's Ok.
