Falling out of love (17f) 2 yrs rs

r/

My bf (18m) said that he just couldnt love me “more” anymore but he still does love me. I know its something that can still be fixed but im just not sure what to say to him because i feel so lost. I love him so much that i want to just keep fighting for it and i just want to atleast try to give him hope (also for me). Can ppl tell me what can be the ways that we can both get better and heal and start to love properly again? Just things that can be used as a reminder and motivation for me to keep fighting and something i probably can just help say to him so that he can also think about it.

TL;DR: My bf wants to end us bcs he cant “love me more.” what can we do to fix it.
