Any good relationship advice for me?

Yesterday…my boyfriend has attended a close friend’s mother’s funeral..who was also like a mother to him.
We were texting and I wanted to know if he was alright. Eventually he told me that he is sorry and he doesn’t think our relationship is going to work because he needs to focus on school where he is lacking and he cannot handle one right now.
I understand that 100%! But do you guys think that the loss of his “second mother” could have affected his decision also? That is what i am thinking. Well, he says he still loves me but wants to be friends and see where our friendship goes. Do you think the loss could have impacted his decision? Also, what do you guys suggest I do from now? I really want to be an awesome friend and be there for him.
I know some of you are thinking that it is up to me, but I just want a few friendly suggestions and shared experience. Thank you!
