bf doesn’t like me anymore

he says he loves me and stuff but I feel such a change. he tells me generic advice and then leaves for hours to play video games leaving me alone whenever I feel sad (bc my depression has been a lil bad lately bc of school)... I can help myself and solve my own issues but it would be nice to have him to talk to. he’s been getting saltier to me lately, not as enthused to see me, and also lately he’s been a little softer when we are intimate. he also barely flirts w me and he constantly jut watches porn. I don’t know what to do, it has me so heart broken bc I love him. he doesn’t rlly listen to my concerns anymore either. feels like he says ILY just to say it so i’m not worried. doesn’t feel real anymore. I need help
