Feelings un a situationship?

So I've been in a situationship for almost a year. We have an amazing connection and are each other's emotional support. The sex is lacking abit and it's at the point where he's mowing my lawns and offering money when things are tight and spends time with me and my son. A while ago he told me when we were drunk he was telling people I was his girlfriend, but took it back a day later when we talked about it sober. I distanced myself for a few months after that. He reached out asking if we were still freinds and that he missed me and was sorry. We started hanging out again and have had sex once. He still does all the things he was doing and sleep in the same bed etc. He wants me to go to his aunts for Christmas but won't come to my family event. I have told him my feelings so he is well aware but says he doesn't know if he can love anyone that way. I'm confused as to why he is still doing things I would consider to be actions of a partner if he only wants to be friends. I have started to withdraw abit to try and emotional detach which have been obvious and less effectionate to match freind zone behaviour. But his behaviour has not changed, if anything he's trying harder. Wtf you know. Guys can you enlighten me on this please?
