He suddenly wants to cuddle with me. Is it platonic or romantic?

So, recently a guy I know initiated cuddling with me. We work together and we're kind of friendly. Then one day he asked me to cuddle and since then whenever we are together he will lean on me or hug me. He's asked me to cuddled twice, and when we did he held me really tight. He loves when I play with his hair and even falls asleep in my arms. He's also said things like he loves how warm I am and that I'm really sweet. What has me confused is he said he's cuddled before (though it's been over a year) and I don't know if I'm just another cuddle buddy or if he likes me. I'm so confused and just trying to save myself from catching feelings and getting hurt if I'm just a warm body for him to snuggle up to and get some sleep :(

When we cuddle he lets me choose the position and if I lay on his chest he'll brush my hair and stroke my arms or back. Or I'll let him lay on my chest and he nuzzles his face into my neck.
