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

So me [17 M] and my friend [17 F] have been talking and just being good friends for a few months now, we went to homecoming together as friends and I have just recently started to think about asking her on a date, but there is a problem.

She and her ex [17 M] aren't having troubles exactly but I think she is starting to like him again and all I know about him is his name and that they dated for a year or so.

So my problem is how I go about these feeling I have for her. Do I try to ask her now and face good odds of getting rejected, wait for the odds to get better, or just forget about this and move on to someone else (but still be friends because I don't want to be the jerk who ignores girls he doesn't get).
<bot>: I [17 M] am have feelings for my friend [17 F] who may be falling for her ex [17 M] again, should I; ask her out now, wait then ask, move on.
