I will be very fast, i met this girl to a party, added her on fb, told her we should go for a coffe she said sounds nice, talked to her on facebook about passions and stuff, so one day i realized the next day i'm free to meet her for a coffe and wrote to her:

"hola S. how did the interview go? I wanna to have a coffe with you tomorrow around 3,30 let me know if you feel like
'wanna to' my grammar is terrible"

she didn't reply to that, and is not signed as "seen", but she was online yesterday so it means she read it but just didn't click on the message so it doesn't appear as "seen"

obviously she is not interested, what is the best thing to say to her now? i was just planning to write something like "hey S. i saw you didn't reply to my message, if you don't wanna have a coffe with me its ok just tell me i'm ok with that "

to be honest i like her but she doesn't seem interested, so if she isn't at least i wanna be the one closing the deal

Man, I would forget about that invitation for now, you haven't convinced her yet that you should meet... Keep up the fluff talk and within a few days, bring up some cool thing you will do tomorrow/next weekend/whatever and when she gives you any hint that she may be interested drop your invitation... make it something interesting like horse-back riding, shooting guns at the local gun range, ATV riding in the woods... Just about every guy and his father are asking girls out for coffee

Yea I agree with Redlight. First, coffee is no good dude unless you are going to walk around and do something fun. Second, an invitation needs to come up while you are talking to her on Facebook not a message. I would try to get her number as well.
