help girls

so my boyfriend of almost 8 months, broke up gm with me last night. he said he didn't feel like he could give his all, felt disconnected and that his feelings changed. what makes me mad is the night before he broke up with me we were hanging out and he couldn't grow the balls to tell me then. i'm not sure if we will get back together or not, but as of rn we aren't. we loved each other so much and we're talking about forever and our lives with each other and idk what i can do to quit thinking about it. do y'all have any advice on new breakups? i'm trying my best to stay positive.
