Is he really that into me?

So there's this one guy I've been seeing for quite awhile now. However we've known eachother since we were kids. Now we're all growm up. And all he wants to do is spend time with me and cuddle up with me non-stop , all day long. It can be a holiday or any reason to celebrate. Its like he's obsessed with being in my presence. He's very sweet and kisses me all over and of course we've been intimate. What dose all of this mean? We've even got into little minor miscommunication however he made it clear he's not going anywhere.
