Is it normal for a male to go off feed when he is introduced to a female?

He was only with the female for two days, then off two days, then back with her for two days.... So a total of 4 days. He never missed a meal before this... and now hasn't eaten since, and that was about 5 weeks ago.

He hasn't lost any weight, and is still active like usual late at night.

Is it likely the breeding attempt that did it? is he stressed out from it as a result? or maybe he just saw that as "winter" and decided not to eat?

any info would be greatly appreciated. My husbandry is by the book. two identical hides, 84 on the cold 94 on the hot. humidity 60%. everything is the same as it has always been.
