Do I send the breakup message?

So I (17F) have BPD and my boyfriend knows, and have been splitting every day over him just not messaging or being with me at all or feeling as if he’s that interested anymore over the last month, and even though it’s because he’s been dealing with a lot of things outside of his control but he never really communicates or articulates this to me for me to understand - instead I just spiral and get into some really dark shit. It hurts because I care so fucking much but I cannot keep waiting in this situation not knowing if and when things will change BUT I also don’t want him to feel as if I’m just dropping him as soon as we hit a rough patch. I recently sent him an extremelyyyy long message just laying out all of my emotions in the most rational way I could and I don’t feel like it resulted in a productive outcome like I was hoping, and although he tells me he loves me and is trying I can’t help but feel like I’d be better off without all of this. Do I keep trying because I do love him so SO much or do I end things? Any advice would be appreciated :(
