Paj Yeeb, whether the story is real and applying to you or not it
certainly portraying many cases that are heppening or happened.

Unfortunately these thing do happen and at time turn ugly. Some of
the participants already share their thoughts and technics that I
myself like them.
Either way, as you said, he is out of control and cannot be convinced
then to go or not to go won't help. Because he will not be happy at
home and may stir up trouble in the house.

I am not sure his friends and relatives are yours or not. If his
friends and relatives are his as well as yours, and they respect you
then they would convince him to take you along or won't let him go
with them. Hmoob kev nrauj pojniam, nrauj nyab yog tag cuab kwvtij
nrauj thiaj taus, traditionally. Yog neb cov phoojywj thiab kwstij
tseem saib neb muaj nqis, respectable, tsi xav pub neb lub neej puas
lawv yuav tsi pub nws mus without koj. Yog neb cov phoojywg thiab
kwvtij hais tsi tau lawm, nws yog dua ib yam. Lawv yuav tau cia nws mus
ib leeg, txhob coj nrog lawv. If they are respectable people.

It also depends on the type of trip / mission he is taking. If it is a
pleasure trip, there is no reason why you are not allow to go along.

If your husband is taking a pleasure trip and won't allow you to go
with him, as someone already mentieoned, you may already lose 50
percent of him. His returning home and be good and faithful with you
depends what he find at the other end. The chance of find good life and
experience at the other end is 50%% of the remainder, which is you still
have 25%% chance of geting hime back in one whole piece. In my opinion,
you can hang on to the 25%% of hope untill he come back and go from
there, one step at a time. But before he goes, show your true love,
affection and cares to him that you love him to the very last fiber of
your life. You also need to make sure and clear to him that you are not
tolerate any unfaithful practice, extra marrital affairs. You said what
you mean and you mean what you said
