Idk about the short lived crush part, but on the no female friends, i think i could help with that? Idk, i have a lot of female friends, probably more than guys. Idk why, i just do ig. Im a straight male in case anyone wanted to know. Idk how i do but ig one thing is, i just respect whoever i talk to and try to be nice to them, even if i dont like them, i still treat them all the same. Also (according to them), im really considerate, so, maybe that has smth to do with it idk. Ironically enough, im an extremely awkward person and could hardly keep a conversation going, so idk how that works out.

So ig, be nice, respectful, and considerate, talk to them as if you would talk to anyone else, dont change who you are, be yourself

Idk if this helps, but, yeah
