Can you be addicted to someone?

OK so I have never thought myself to be clingy but recently I have like this craving or intense need to be around my fiancé all the time. For about the past month I've noticed that I get extremely sad or down if I don't get to see him for a while. We see each other pretty often, right now our work schedules don't match up but we get a few days off together but idk I just want to be next to him all the time and it's starting to annoy me lol he says he's fine with it and that he'd rather me be clingy than not but I don't think I should feel that sad when I'm not with him idk sorry this is long so yea what are your guys thoughts?
