Awfully complicated, and I need relationship advice, and I really need it..?

Very awful situation you've encountered and I am glad you're able to keep your head up. You understand you've been lied to which no one deserves; you were manipulated and only someone with the heart of ice, or of course serious mental issues could follow through as long as this individual did. My advice is to move forward with your life and heal that broken heart of yours because right now you need to focus on yourself. You need to focus on what you CAN do and what you CAN do it move forward. Whether you can be friends is a road you'll cross at some other point, but right now that'll never sincerely work while being as rightfully upset as you are. Forgiveness will take a very long time and it's a hard trait to possess, so focus on yourself right now rather than her. She's hurt you and she should be thankful you're not malicious over this - wish her the best and focus on healing that heart of yours. Once it's healed, then maybe you'll lend it out - even if a little bit - to her someday when you're able to forgive. People try rushing this and it usually ends in a disaster - save yourself the agony. Facebook.com/Ejayrazz if you wish to continue this or need anything else. Above all else, don't be shy as I've worked with thousands. Best of luck to you!
