The choice

Hey everyone. So my name is Sara and I’m posting this because I need some advice. And I don’t really know who to go to. So the guy I like likes me back and we have a thing now... but he also likes this other girl and he doesn’t know who to pick. I told him that it’s his choice and to give me a month to prove myself because him and the girl he likes Have has a thing already and we haven’t. He’s giving me a month to see who is better and I don’t know what to do or say.. I was this month to be special and I want to prove that he should pick me but he doesn’t really text me because he’s always busy. I need help with figuring out how to flirt with him and get things up a lever before the month is over.
