I disagree, with one caveat... We haven't heard his input.
You list yourself as a stag, which means you're a cuckold who hates the title because you don't identify with what mainstream porn has attached to the term "cuckold". Stuff like humiliation, denial, chastity, sissy/bi/cross-dressing, etc. So to you, and maybe many others, it appears as abuse and manipulation.
To a cuckold who has an interest in those other branches of BDSM, it's not abuse or manipulation. Or, it is, but it has become a turn on, or part of the dynamic between husband and wife. There are plenty of couples on here who have those dynamics who still truly love each other.
But back to the point... if we could hear the husband's opinion, it might help shed some light on if he loves that she does that to him, or if he hates it deep down inside... or maybe both. A cuckold can feel jealousy, resentment, love and lust all at the same time. The love and lust are the ones that win out for successful cuckolds.
