Ok so I have this friend. We are sophomores. I absolutely consider her my bestfriend. Here's some things you should know about her. She is a big tomboy. Like majorly. She dresses like a Guy. Wears Guy clothes and sometimes get mistaken for a being a Guy. So she has instagram and she has everyone blocked from our school including me. I am 99.9% sure she is also pretending to be a Guy on instagram. I know this cause I made a fake account to follow her just cause I can (don't judge) people call her Alex all the time. She put a pic on there telling people to follow her new twitter and her twitter name had the name Alex in it. And she also has this thing with a girl on instagram but I'm pretty sure this girl thinks that my friend is a Guy.. but anyway my friend never texts me first. I always have to text first. And if she does answer its only for like 5 min. Then she stops answering. So like Friday this girl she has a thing with told her that she thinks she's falling for her ex again. Well my friend got super upset and was crushed. So technically they were done talking. That was Friday. Now all weekend my friend has been texting me a lot and texting me first like all weekend. But Sunday she stopped texting me back or first. I checked instagram and her and this girl seem to be talking again and all Flirty and stuff. So did my friend just basically start texting me cause she couldn't talk to the other girl. Like was I a second choice. Idk what to do. Please help. Cause she really is a good friend but I don't like feeling like a second choice. What would you do. Please helpp??
