So I went on day 3 with this HB, ended up fingering her, then she txted me right after when I got home. I txted her again 2 days later making fun of the hickey she gave me. After a few replies, I fell asleep. Didn't talk to her for couple days till yesterday, after I took about 3 hrs to reply her back, she replied with kinda a bitchy/jealousy attitude, we were joking around so I didn't call her out on it. Next thing I know she didn't reply. So today I sent her a text asking what sort of trouble is she causing. No response.
I'm not sure if she's throwing a tantrum because I freezed her out for couple days or she's trying to pull some BS. It's getting on my nerves since my game in person is quite good enough to get her hooked, she pretty much all over me and didn't wanna leave at the end of the date, however, she always acts totally different after a few days not seeing each other.
I need some advice on how to deal with this type of girl.

PS: While we were on the date, another HB was hitting on me while she was in the bathroom, she came out and saw me talking to her.
