If this was you, what would you do?

Move on.

If he broke up with you, he broke up with you.

That means he doesn't want to be with you.

Do NOT read into the whole "let's still be friends" thing. That does NOT neccessarily mean he is 'leaving the door wide open for you two to get back together. Period.

Unless he tells you something point blank (e.g. "I want to get back together") do NOT ASSUME it. It will only lead to hurt feelings on your side.

ETA:
I think it's great he has been there for you during some down points in your life, which really confused the whole situation for me. If he is 'going through some stuff' and you are 'going through some stuff' I guess I don't understand why he wouldn't want to stay with you so you two can help each other out during tough times. I obviously don't know the whole story, but I get the vibe he is using his 'stuff' as a cop-out excuse to break up with you.
