do you think a girl who used to like you would still maybe go on a date with you if you ask her?

maybe.

You can try it but when timing is off you may not get the best answer. Why didn't you ask her out when you liked her? This happened to me and it just made me mad that it took him so long. It had taken me that long just to get over him and he tries to mess with my feelings again. I am not saying you shouldn't try just know that it is a possibility.

Yes if they are still interested in you, or some kind of special affair came up and they had no one to go with them.

Depends. Did she really like you? If so, I reckon she still might. But she might also have gotten over you. Really depends on the paticulars.

depends if they still like you and they havent moved on

depends on whether she gave up on u totally or not
