If he wasn't around to help with the home and his children I can see why she wanted a change . That’s a bit harsh. We don’t know why she left this man - and her children, if i read it right - but we must assume that when they married she knew what, as a service wife, she was letting herself in for - periods of separation, for certain; living in married quarters, for certain; the claustrophobic environment of a service community, for certain. It’s not about feeling sympathy for either of them. That’s not what the OP is asking for. She doesn’t want to be “getting a taste” of anything!
