<human>: Can you condense the text into three sentences or less?

I [19/m] dated a girl (19/f) earlier this year for about a month and we had a ton in common and got along great.  Then abruptly (from my perspective) she seemed to start avoiding me so me being the arrogant boy that I am decided "well two can play at that game" and no surprise we stopped talking all together. Now within the past few months we've gotten back in contact and even though its never been more then small talk, its always been friendly and sometimes flirtatious. However Ill get to the point; I really like her and it kills me that we aren't together.  She hasn't (to my knowledge) been with anyone since we stopped dating and I (even though I must admit I am a bit biased) feel that she also still likes me.  The problem with the situation is she has well known commitment issues (she said so herself) and it was probably the reason she started avoiding me in the first place.  I have no idea whether I should make a move, lay all my cards on the table and see how she reacts.  Go with the status quo and see if something out of my control changes.  Or if I should just try to move on and forget about her. 
(any advice would be appreciated and if additional details are needed ask and I'll give them.)
<bot>: I need advice on what to do about me and an ex with commitment issues. (sounds original and unique I know...)
