Not that he's 'realistic', but maybe he isn't really the kind of person that falls in love before or right after starting a romantic relationship?

I'm not really sure of what to say other than that it's up to you, as you've known each other for only a few months, maybe it worths a try to establish a deeper connection? I'm sorry that you feel hurt, I'd feel just the same.

And sorry, I got it figured that it could cause you anxiety as you said you rely on him for social interaction.
