Am I using him or he just a bit to much?

I am just getting back into dating. I am an older women with 2 children and recently starting dating a much much younger man. He is very caught up on me and calls and texts all the time. I felt like it was moving fast than what I was ready for and told him this. I ended up having a bad day and calling and hanging out with him. He ended up surprising me with a very expensive ( $250) gift. I didn't feel right taking it and gave it back to him. He ended up returning it to the backseat of my car without my knowledge. I don't know where he lives so can't return it that way but I really think we need to slow down and take a few steps back. How do I tell him that or should I just ignore him?
