Shall I just let go?

My SO and I are separated but live together at the moment. He owns the property we live in and bc we have children he said I can stay there until I find somewhere. We have seperate sleeping arrangements and there's obviously no intimacy but other than that its like nothing has changed. He comes home from work and tells me about his day, he tells me about his projects he's working on and asks my opinion, I still do his laundry and cook meals. We still laugh and joke like we did before our relationship turned toxic and shit. We're both individually working on ourselves and still love each other. We just got into a rut and the relationship went bad. We even share a bottle of wine or two together sometimes and enjoy each others company. We sometimes talk about past holidays and memories and we'll joke about other stuff. It makes me start to fall back in love with him all over again, I wonder if he feels it too? The thing is he's not much of a talker in that sence. He won't communicate about feelings etc he just shuts down so I try not to bring up 'serious talk'. I do sometimes send him little quote images through text, basically just telling him he's my best friend, soul mate and all kinds of things like that. He doesn't reply but he replies to normal messages. As a sufferer of anxiety and depression I read so much into the non answered messages and see that as my cue to leave things as they are and move on. What do you ladies think??

Eta: he already knows how I feel. I've done and said enough to let him know. The quotes I've sent him were just cute little reminders just to let him know when I'm thinking of him etc.
