AITAH for calling my ex when I have home maintenance issues.

I got divorced 3 years ago. I kept the house and my ex moved out. I live with my boyfriend of 2 years, he's great. However, he has never owned a home and is not at all mechanically inclined.

Whenever I have a question on home maintenance issues, I'll call my ex to get his advice. We have an amicable relationship and get along well. My ex and I lived in the home for 20 years and he knows all the little quirks.

My boyfriend gets a little pissed over me calling him occasionally to ask a question. I have never given my boyfriend any reason to feel insecure, but aitah for occasionally calling him?
