It depends on the reason you broke up sometimes, in general breaking up a number of times over the small dumb ****...just move on because you need to think to yourself and ask Do I really still want to be with her? Or am I just missing that company and want her there? Girls fluctuate with their emotions a lot, so they confuse you and most of all sometimes they don't even know what they want which clearly shows in what you jus described.
What you want sometimes may be your brain only seeking the comfort and satisfaction. But what you really want to do with your gut feeling, instinct and heart is reality.
