Is she hiding something from me?

[GSN]

So me and my gf have been going out for nearly 2 months...and we are both in college...im her first bf.

So some context before i explain my current situation

A few weeks ago she told me how her family had switched carriers and her phone would stop working for a few days. I didnt believe her. I felt like she was trying to make an excuse to stop contacting me so she could see someone else without any distractions. It turned out that she actually did get a new phone.

So today she told me her brother is coming to town this weekend. And that i wont be able to sleep over at her place this saturday night. She said that her bro was in town to meet some friends and might stay at her place. But saturday night is the same night there is a concert we are going to and an afterparty. We are both going to go together. But i have my suspicions again that maybe her brother is NOT really coming and she might be meeting someone else later that night...

In addition she said that her brother is going to come for a F1 race the following weekend. So it doesnt make sense to me why he would come both weekends...

Reaons why i feel like i might be overreacting:

- she really hasnt given any signs that she might be cheating...she lets me see her texting her friends on her phone...and she opens up facebook in front of me regularly

- she has introduced me to friends...
- she has put a pic of us together as her prof pic on fb...with her brother even liking it and her other relatives (cousins/uncles/aunts) liking it as well
- she has held my hand in public...even kissed me and even hugged me
- she texts me daily and if i dont reply back right away she gets worried and starts texting me uncontrollably
- she stated a few weeks ago how she didnt understand why couples cheated on each other...she said that an individual should have the balls to tell their partner if they dont want to be together

what do you guys think?

You should talk to her on while she is acting like that. Whatever happens, you shouldn't assume much and do anything rash. Just notice a few more things and then try to talk to her. Maybe she's planning something special for you? Who knows? Just talk to her.

Answer my question?
