Need advice for a confusing good term break up

Sorry this is a bit all over the place. My now ex boyfriend 25M ended it with me 19F 4/5 days ago. As much as it still hurts I completely understand why he made the decision. He needs to focus on himself, as do I, and that's ok.

We live together so not only have I had the thought of losing him on my mind but also my home. We've agreed distance is needed but he as reassured me all my belongings will be untouched for as long as I need until I have somewhere permanent to live.

The first two nights were awful, alot of inconsolable tears from me. (This break up brought up alot of emotions from traumatic experiences growing up). He was so patient with me through this and was as comforting and caring as he could be while keeping his distance. Night 3 he stayed the night at a friend's so we could both have some space which was very needed but when he came back the next day I couldn't take how distant he was being with me, which again I completely understand why but it still hurt. It felt like he was a hologram and every time I tried to touch him my hand just went through.

I figured I had to leave the flat which really I should've done on the first night but I couldn't bare leaving my safe space, my home in such an emotional state.

During those few days we made it clear to eachother we care and we love eachother (this was communicated healthily, not in a mindfucky kind of way). It's so bittersweet knowing this, it would almost be so much easier if we hated eachother but at the same time I'm so appreciative of the fact that we're good. Yes we're not in a relationship but I haven't fully lost him, he isn't necessarily going anywhere. I had a moment where I told him we couldn't be friends because it would hurt to much but not long after I said that we could be friends because he's too important to me and he agreed. He said this is the first time in a breakup where the other person hasn't hated him or he hasn't hated them loland the first time it's been on good terms which means alot to me.

We saw eachother today (after only leaving last night) since we had it planed anyway. We walked around the park in the area we grew up in and just talked. When we first met up we were both a bit awkward/hesitant on what to say but very quickly we were talking and joking like normal, I thought I'd have a negative emotional reaction to it but the whole thing was actually very reassuring and comforting. It was so nice to just be with him and to have some sense of normality. By the end it felt like he was trying to make it last a bit longer like taking us down a much longer route to leave the park when we already decided we were leaving through a quicker exit, then when we'd left the park he suggested walking a little bit of the bus route before getting on the bus (I know he doesn't like being alone, especially after the fact we've been by eachothers side nonstop for months). He walked me to my next bus stop and waved me off, as he did he looked so sad and it really hurt to see.

During one of our conversations we'd planned to see eachother in 3 days then decided it would be better to see eachother next week instead as to not push anything. We've also planed a day in the next week or so for me to go over and get ready for a night out then stay the night when my night out is finished since our flat is in the city so this would be more convenient but more importantly, it would be safer than me getting back to where I'm currently staying. I'm very relieved we have some sort of plan/structure as to what's going to happen for now moving forward.

I think in the first few days I got over the worst part of my negative emotions in regards to not being with him anymore but since I know we're ok at the moment I'm not as upset at the moment. I know this will take time to get over. Now more than anything im homesick. I want my bed and my space so much it's killing me.

I'm not looking for reconciliation, I am however really hoping he can stay in my life because as I said, he is extremely important to me and I cannot fathom life with out him being present in some way. He's even said when time has passed I'm more than welcome to stay on the spare bed if I need somewhere to go.

My fear is as our connection is still strong this could all go wrong very easily. I understand limited contact, distance and boundaries are vital for this but Im worried about emotional slip ups from either of us. (Saying things we shouldn't in moments of weakness, that sort of thing). If you've been in the same or been in a similar position how did you get through it and where are you now as a result of that? How can I keep this positive and healthy for both sides?

Little details that might be important: I have a feeling people might come for the age gap, there was no power imbalance and he treated me the best I've ever been treated by a man.

We established straight away no intimacy of any kind as that would be extremely harmful to the situation.

We're both AuDHD and share very similar difficulties growing up so mentally this has been taxing on both of us in ways that would be different for someone neurotypical or someone who had a stable upbringing.

The breakup was no ones fault, it happend over unhealthy coping mechanisms from both sides.

We were with eachother for just under 7 months but were seeing eachother for 3 months before hand and were with eachother everyday.
