Hey guys
I am in a very confused state and don't know how i should go about doing this. So i met this girl (HB

through my older sister. They have just became friends so they hangout a lot. Now my cousin and her friend are older than me. Although I dont know her exact age but i can assume that she is 5-6 years older than me. Anyways so me meet one day, get introduced and start gaming her just for the hell of it. I did not think anything would come out of out it however she was responding well and I was getting few IOI from her. For example her maintaining eye contact, hitting her feet with mine etc. I was being my usually C&F and time would ignore her, like when she would be talking I would be looking else where as to not give her too much attention.
NOTE: this girl gets alot of attention from guys eveywhere she goes as she gorgeous. She also claims she has a bf who is very famous celebrity however this is not confirmed.
Anyways so she gives me her number because of some favor she wanted and adds me on fb. Since that day, she has messaged/text every day for some reason or another. At times for the favor she wanted and at times just randomly. Now I am a little hesitant to go after her because of the age difference but thats not the issue. Now she texted me last night asking about if i know some other guy however i did not respond as I do not want to be available all the time.
Questions:
Should talk to her everyday or space it out to make it seem that im not always wanting to talk to her?
How should i go about gaming her as I am not sure whether she is interested or just being friendly?
She told my cousin that she likes me but I am not sure in which sense?
Any and all comments are appreciated.
