Weird sugar daddy situation

I met this guy on a website saying he was looking for a sugar baby. I had thought about getting a sugar daddy and giving it a try. Idk what exactly I expected from this man. I'm 21, he's 47. But this whole sugar baby thing is nothing like I expected. I think he's just... Lonely. Because since we've met and stuff he's never said anything sexual to me or flirty. He mainly wants someone to play board games with and talk to. Thats pretty much all we do. He vents to me about stuff. About missing his daughter and since she became a college student it seems she rather have fun with friends than visit. He sends me gifts and money and in return I just listen to him and hang out, talk and play board games. Thats pretty much all I do. I'm wondering if he's trying to make me a replacement for his daughter
