What does it mean when an ex bf gives his ex gf back massage still... normal or no?

So I guess I thought this was weird. But what dose it mean when your ex still wants to give you back massage when your not dating. Like my ex bf and I have been on an off with each other every since him an I broken up for the 3rd time this happen like last year. But somehow we find a way back to each other, I mean yes I dated an liked other people afterwards, and he has dated an liked other people as well. But I notice when we do come together again! we hang out like old time's, and have fun :) but some how end up having sex like lol. And even tho him an I are over an done, I still feel like were a thing just without the label an commitment. But when him and I do hangout, he still kisses my hand the same as if we once was together, he still looks at me when we are next to each other, he still wants to hold my hand as we drive down the road. But Just on Monday was a bit weird for me I don't know for him but for me yes. Like he was begin super sweet, and nice, an cute! and that was fine. But he always comes to me for sex or looking for it. But after work we went back to his place an he asked me did I want a back massage and I was like sure only if he wants to give me one. THEN HE SAID yea sure he didn't mind. But before the back rub he was like caressing me on my arm's, but at this time he was lean in towards me like standing on the side of his bed. And then when I asked him to get on the bed with me. And we was laying then side by side an looking into each other eye's like just laying there on his bed. And even before him an I went to his room we was in the living room at first like- and him an I was just talking, an making out like. But he kept holding my hand like an a sweet way! but laying his head on my shoulder. by the way my question is this all weird an dose other ex gf's or bf's give there old ex a back rub and all these other stuff to?

Him and I are still friend's :) Thank's
