Can a Bull be proud of a cuck?
In answer to your question, yes, a Bull can, but only if the cuck gives grounds to make the Bull proud. He has to work hard to prove he's worthy of the Bull's pride, and that of the Hotwife.
I've been fortunate in having a very long term relationship with a married couple. She has blossomed as a Hotwife, he has developed well as a full blown cuckold. He had to be carefully taught his role within the cuckold marriage, just as she had to be taught her role as a slut - both have learned well.
So yes, I'm proud of my cuck, and even more so of his wife.
