so, a little background, i broke up with my ex around the end of sept, but we never really broke up. i moved out of the house, but we still hung out plenty and had sex on a regular basis. i have been telling her that i want to get back together, i noticed some mistakes i made in our relationship, and have fixed them, etc. i have been the dream guy the last 3.5 months (but that also means i havent been any challenge at all ) so i am thinking about giving her an ultimatum tonight. we havent spoke much this week, and so i was going to tell her that our relationship as it stands isnt working for me, and that i need something moar. if you dont want the same thing, then we should stop seeing eachother. or something like that. i guess i want the vag's thoughts on ultimatums, are they effective (especially are they effective to get desired results), and if you have any tips on how/what to say. sorry if this post doesnt make a whole lot of sense, i am rushing to get out the door, so i havent been thinking about what i am writing a whole lot.
