is it worth a second shot?

if u think its gonna work go for it but maybe at first u should ask her if she wants to go somewhere jus to hang out and if she ask's if u mean like a date say no jus as friends

Yes a second shot

I would talk to her about why she dumped you first. If the reason she dumped you is still a factor, you could wind up back where you are.

this happened to me but i didnt give her a second chance because im the one who dumped her (she was holding hands and flirting with another guy) anyway, it also happened to me another time, and i did take them back and are with them for the past 5 months now, wonderful relationship the break up in the first place was kinda misunderstood so i say it depends what you broke up over
