Also i read "thank you for being my friend" part as her thanking Jay for approaching her when they first met. This doesnt mean they arent something more. Even they said "we are just friends", you could read them as "roommates". "Oh yeah, they kiss, date, do everything together. Its a hommie stuff. Certainly not lovers! They are just roommates!" LOL.

I read to the end. Even though they didnt officialy said that they are couple, they clearly are couple at the end.
