Miku expo made me break up with my long term bf

Miku expo made me realise I was putting my bf before myself in our relationship. They're genuinely a good person but never really took the time to understand me. My best friend, sister, mother and random people on the Internet keep telling me to crash out of that relationship but idk. Cause, I've had worse exes (The liquid shit guy) but this guy is genuinely making me sad and just leaving me on read when I try to talk things out and try to covey how I'm feeling. I'm always there for them but they're never there for me. God being gay is difficult
