what does it mean (her reply)?

Okay so i asked this girl to prom over twitter, in a cute way she told me to text her. So i did. We talked and eventually:

Her: Look that was super sweet and no one would ever do that for me trust me im so flattered and really appreciate it. But i really just planned on going with my girls and having a relaxing night. Its just that we arent that close im really sorry.
Me: I know i mean id just want to go as friends nothing more or less, it would be fun i promsie. It wont be anything crazy just a simple night. Photos, hangout at prom with whoever and thats it. really whatever you wanna do. Trust me i know where not that close.

Her: i know you mean well its so sweet but i think im just gonna have a girls night.

Me; I understand but just think theres always girls nights. Theres one prom, we would have fun and its not like im trying to drag you away from your girlfriends or anything like that for that night. We'd all chill and ****, if you say no ill leave the topic alone but you should say yes.

her: can i think about it and let you know tm

MeL yea np, i know its a tough decision but think of all the people youd make happy (well just me lol). cheesy huh?

her: lmfaoo yes very..

me: well think on it but if you dont want to go with me just say no straight up, i dont want you to not have fun.
she said after shed let me know tm

I personally think she wants to ask her friends but idk if she just said it to get me to stop asking about it or what. What do you guys think, i think the fact that i got from no to think on it till tm is somewhat good i dont know thou
