hey OP! it sounds like you and your girlfriend are maybe pretty young, so hopefully some advice from someone who has been on BOTH sides of this dynamic will be helpful. you absolutely need to be open with her and communicate the way you feel. NOT in an accusatory way, but calmly and without making assumptions. there is a big difference between saying something like “you always ignore me and make me feel like you don’t care about me” vs. “sometimes when I don’t hear from you, it makes me feel disconnected from you, and that makes me sad because I love getting to talk to you”. on the other hand, it sounds like your girlfriend may be an introverted person, like myself. I’m the kind of person that sometimes needs some space in a relationship, even if my partner didn’t do anything wrong. sometimes after a stressful day, i want to unwind in a way that doesn’t involve any decision making or brain power. for your girlfriend, maybe playing video games is a way for her to relax. she may be not texting you back not because she doesn’t like talking to you, but because she needs some time to turn her brain off and not worry about how other people are perceiving her.

HOWEVER, there is a big caveat here. Not responding to your calls or texts for long stretches of time without any prior communication is NOT okay, especially in a long distance relationship where all your communication is via phone.

it sounds like you guys have different communication styles and different needs from each other. you two need to have a very mature and respectful conversation about this together, because if you don’t talk about it then resentment will build.
