One of my friends I’m super close with and recently we’ve been messaging lots and I’ve driven up to her town 3 1/2hrs away to visit many times over the past few months. 
She hasn’t messaged me back in 4 days, even though I know she’s always on social media and she’s currently out with our other mutual friends who are talking to me right this moment on social media.
We do have amazingly fun times together but sometimes I feel like she only wants me around when she doesn’t have anyone else.
I’m probably being a bit unfair but I find it hard to deal with my own feels of hurt, jealousy and rejection. I just want to scream and cut off contact, which is dumb. 
I’m not sure if I should message her on Monday asking if she had a good weekend, or if I should wait for her to respond to my previous message. I’m afraid that if I wait on her, she won’t message me back at all.
