AITAH for not wanting to text/call my bf multiple times every day?

My boyfriend is constantly texting me from the time he wakes up until he falls asleep. He calls me multiple times every day. I reciprocate as much as I can but it’s exhausting and I feel like an AH for thinking this.

If I don’t reply within at least 15 minutes, he will text things like “good talk” and “guess you’re too busy to talk to me”.

I’ve talked to him about this in various ways and he will tone it down for a day or two and then goes right back to it.

We have been dating for 5 months…
