I really liked a guy

So I am a Marwari (Doing radiology residency).My father is looking for prospects in arranged marriage.There was a guy I talked to a few months ago and we both realised that he is still stuck on his past(who got married btw).Which is why we stopped talking.At least I think the reason was that he wasn’t ready.But I am still stuck on him.I haven’t clicked with anyone the way I clicked with him.It’s been months,but I am still not able to forget it.It’s over from our family’s side as well.But I am still stuck and unable to get out of it.He pops up in my head every now and then.What should i do? I would really appreciate advice from everyone .
