Broke up with boyfriend HELP

So last week my boyfriend of 3 years (and first love) broke up with me. I cant explain it, but he was my person, we were so close emotionally, and I’ve never met anyone else who clicks like we did. He is at uni away from home, and i will be going to uni away next year. His reasons for breaking up with me were that we just have different lifestyles and enjoy different things - his love for partying and going out vs my more calm and relaxed life - not to say i don’t like to go out, just not every night!!!

He mentioned he wanted us to distance ourselves to help him get over me, which I have respected since we broke up.. but i cant help but wish we were still together. Surely our love for each other is stronger than our differences ?? He said he is still completely in love with me, and i have no reason to believe otherwise, as he has always been obsessed with me. I still love him too, and I feel hurt that something so petty has got in the middle of our relationship, especially as I didn’t say anything or defend it when he stated he wanted to break up (kinda just sat there in silence because i was so shocked).

I just don’t feel like it was a valid enough reason to end such a strong relationship, and i feel like if i knew it was such a big deal, i could’ve done more to make it seem less so.

Do i try and get over him and move on with my life, or do i try save the relationship?
