AIO for wanting a bit more of attention from my bf

Hi everyone <3,

So me (18F) and my bf (19M) have been together for 3.5 years and these past few months I feel like we have been distant. He can be very busy however he has been texting less and often never text unless i text him first. I have mentioned this to him twice already and he apologised however nothing changed. Tbh he has a lot going on in his life right now and it is affecting him mentally yet he refuses therapy and i don’t want to be narcissistic and force him to give me attention but it would be nice if he gave me like a heads up and even a short text asking me how i am.

I don’t know what to do and i want unbiased advice (sorry for the terrible English its not my first language)
