what should i do?

i (25f asian) had a crush on aussie - pretty handsome, smart (29yo) for over a year ago. we did not hang out/ flirt... just texting but not work. he just asked me out for drink few times and one day he asked "what would it be your ideal outcome after grabbing drink together?", that moment i felt he just wanted to hooked up or he thought i was cute so i tried to be silly, didnt answer in a serious way. its been a year so i still regret why i did not tell him i liked him or at least hang out.

i just moved to aus for 2 years and im really into with aussie, be honest that guy made me feel butterfly in my stomach - its been a long time since I've felt this way.(ppl say i'm cute, good-looking, tall)

now i'm dating with another aussie and we had a strong chemistry on the first date. we are not in relationship yet even he asked me many times, because i felt he cannot handle himself (struggles from work,...), his family is a bit complex. overall, he is a nice guy with caring, clear communication and generosity.

at this moment,im still thinking about my ex crush just dont know how

im hanging out with this one but inside me kept thinking about the old one who i had never hang out yet. will i never move on from something i want to try?

i want to ask you guys do you have exactly types of girls you want to hang out or dating?
