Any advice for the newly brokenhearted? For someone who was talking marriage one week and broken up the next?

Hey i understand where your coming from. Im not trying to sound harsh in any way or offend you but when a guy says he needs space that means he wants you to stop talking to him for a little while so he can clear his head. If you keep bothering him, he'll think your clingy and push you away for good. So give him time, turn your phone off, dont go on the computer. And then in a month or so text him saying "hey how have you been?" dont make a 5 page long message because he would think you were being desperate. im sorry for you but hang in there! and good luck hun :)
