Oh wow, I haven’t dated in more than 11 years but this sounds so annoying. I’m sorry he’s putting you through this, really. I hate men that can’t commit. In my opinion, ask him to define the relationship you all have. Ask him first so you can understand where his mind is at and you don’t have to walk into something you weren’t ready for if it’s disappointing.
In my opinion, I’ll have to disagree with Aurielle, you all sound like you’re already dating. A long time ago, before I’ve been exclusively serious relationships, two back to back in the past 11 years, I would hardly ever sleep over at someone’s house when we’re just sleeping together. I’d always leave before the sun came up, because back then at least. Staying after the sun was up meant you’ll were serious about each other. And IF I ever did, mostly it was cause I was reading the situation wrong and he wasn’t interested in a real relationship. But again maybe times are different? Definitely ask him cause it’s such torture just to wait and see what’s gonna happen between y’all I’m sure. Good luck and hope it works out!
