Me and my gf are in high school and we've been dating for 2 months. Its currently winter break and shes on her last day of visiting a different city before she comes back home. We text or call everyday. 2 days ago she sent me a selfie on snapchat that was only for me. When we were talking on the phone I called her out jokingly saying she was trying to show off her ass and she jokingly denied it. I then said "u probably pose for everybody like that" and she said "no only for you cuz I love u". Today we were texting while she was going to the mall and I was teasing her saying that she has buying problem and that she buys anything that catches her eyes. She said that wasn't true and proving while it wasn't but i continued teasing her but eventualy said i was joking. Then All of a sudden she said she'll talk to me later and I said "awh ur just gonna leave me like that?" to which she replied "theres no point in talking to someone who doesn't listen" and I said "but I do listen". She then said that shes done with my teasing and that I can talk to her again when i respect her like i did before i we started dating. I've texted her a lot since then on both imessage and snapchat saying that im sorry and that i really love herbut she hasnt read any of it. Its been 4 hours and she normally checks her phone often so I think she might be ignoring me. Idk for sure if shes mad cuz shes normally really playful and teases me a lot too and ik she can take a joke. Shes never done this before except for one time when she acted mad and ignored me for 10 minutes as a joke. Is she mad at me and what do i do to fix this?
