Need some advice

Salaam honey, please reread the above quote which you wrote. Its not healthy to continue a relationship in which you hate and loathe someone so much. It seems the only reason you want him to come here is so your parents/family SEE the type of "animal" he is. All you want is to take out your "revenge" on him.

I understand your parents want to give it one last try, but it will be so complicated once he is here. I'm not sure which country you live in, but if you do decide to bring him here, do not give him a stake in your house/assets. Also remember you may end up paying spousal support, if he cant get a job because of his lack of education. It is not your responsibility to support your husband.

I honestly think you should pray istikhara but I personally would not even involve myself with visa applications and end the marriage altogether. There are so many signs that this marriage is unhealthy. InshAllah, you will find the strength to leave and find someone who is similarly educated and kind. Once he is here, things are most likely to get worse rather than better.

I agree with what redvelvet said below, if you get pregnant again, you will be tied to him for life and there is no way out of that situation.

I'm not sure what zaath is, so I cant comment on that... I will keep you in my duas.
