But generally speaking, if you have been dating someone for over 3 months what should you expect?
I've only been in one serious relationship in my life if you can call it that. I don't know what normal communication or anything.
After a 3 month period now you're wondering "what we are", then it's usually not a progressive relationship.
Progressive relationships typically involve serious and clear intent and communication/expression.
You'll just find yourself questioning his actions/behavior, being "confused" and then ultimately investing more and more "hoping" it is a progressive relationship.
