<human>: This year I made and lost my first girlfriend, am thinking about the second, not sure if I should proceed

Got introduced to a bunch of people that I didn't really hang out with before, got pretty close with one of them and asked her out, but broke up about two months ago after three months of dating.

The other girl has been pretty close with both of us through it all, my ex is still pretty good friends with her, but not super close.

In this time the group fell apart, and now I want to ask the other girl out, maybe to prom when the time comes, but idk if its socially acceptable, especially cause the other girl is friends with my ex.

I'm not desperate to go out with this girl, and I don't want to seem like a jerk by asking her out after breaking up with a friend of hers. If its not cool, just tell me and ill lay off, don't sugarcoat it

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I broke up with a girl, want to ask another girl out, but girl 2 is friends with girl 1 (ex), not sure if socially acceptable (in high school)
