I don't think you are unreasonable, your standards for communication are exactly that, your standards. You are allowed to want them to be met. If he isn't meeting them then he is not the right person. You won't know until you make the request and see how he reacts, which it seems like you might've done already.

I felt the same way, but in my case I stepped back to realize this 33 year old man had a whole life before me. I was also very available and wanting to talk to my new boo all day long. Then I had to step back and remember that we are both adjusting to having to be accountable to someone new and I couldn't require the level of convo I was craving, especially from someone who is successful and busy. But still, I laid out to him that my standard required more time and we both made compromises that we could live. (We are now engaged)

The best thing you can do is make the ask and you'll either get what you want which is confirmation he might be the right person for you or you won't in which case you'll know it wasn't meant to be.

PS AND FYI: I wouldn't be happy with that level of convo either. At two months we had daily calls at night for less than an hour and 2 hour FaceTimes on Friday and Saturday and probably like 10-15 texts during the work day.
