Boyfriend or fuckfriend?

So, I started seeing this guy a couple of weeks ago. He said that he's a serious kinda guy (he's been in years long relationships) but just found out that his 3 year long girlfriend cheated on him. I've never been in a serious relationship and I'm tired of fooling around meaninlessly. The thing is he wants to take things "slow" because of his now present trust issues. We already slept together, he calls me "baby" ect. , and cuddles with me. But anything other than having sex, he's not really into it...So I need to know what y'all think about this and how can I know if he's willing to be in a relationship or not.
