Lies... am I crazy!!

So I always call my husband after I’m finished at work, to see how his day is, and to see if he’s almost done! He gets done at all different times! But today I call he says “I’m busy working, I’ll call back in 10 minutes!” Something sounded off so I called back but no answer! So I tried a quick text “I feel like your lying you didn’t sound busy you sounded sleepy!” (I know the man 3 kids and 14 years together!) He replies “busy I’ll call in 10!” Okay! Then I find out he’s just sitting in an empty parking lot!! So I call back pissed that he is lying!! No answer. Finally on the fourth try he answers! “What I said I’d call you back in 10 minutes you can’t just wait!” He says! So I tell him “ your lying your sitting in a parking lot” he reply’s “so what I didn’t wanna talk told you I’d call you back in 10”... needless to say he sat in the parking lot for 20 minutes says he wasn’t doing anything he was by himself and just didn’t wanna talk!.... I’m so upset and thinking all kinds of crazy things! He says I’m being crazy and making a big deal of nothing!?!?! It just doesn’t make since to me we always talk at that time and we were good completely happy that morning!!!! Help am I being crazy!?!?!
