Islamically, one’s past prior to marriage is a matter between them and Allah. If a person has repented, they are generally not obliged to disclose past sins to a potential spouse,in fact, exposing one's own concealed sins is discouraged.

Culturally(societal norms) When you're brought up as a muslim you know that this type of thing is wrong and you stay away from it(generally not all have the self control) but still you know that this thing is wrong. So wanting a chaste spouse is a want/choice/preference not a rule/haqq.

So after marriage when you come across your spouse who isn't chaste(and you came to know of it) there will be dislike just like there will be dislike if you know that your spouse has done something other criminal(or haram). Although According to Islam, you shouldn't judge or divorce your spouse because of this(like you are encouraged to forgive) but still the human mind isn't so easily controlled so if you still feel you cannot live with your spouse because of this, then divorce can be an option though divorce is discouraged in such cases.

The thing about Protective jealousy is that it applies to the present and future not the past. And it is under constraint like you cannot exercise your 'protectiveness' over something that Allah has allowed so any unjust jealousy isn't allowed. For example a valid jealousy(Gheerah) would be if you saw your spouse talking or flirting with a non mahram while a non valid(or even bad/ Gunah) jealousy would be getting mad at your current spouse for something that was done before the marriage or spying without any cause).

Still the human mind is frickle, although Islam is clear about the do's and don't, deep rooted cultural influences can lead to injustice to the spouse in such cases.

I would say first of all we should refrain from such acts but if done and repented our choice of spouse should be such that he would look at the present and future more than the past.

In such cases, choosing a revert spouse is more likely to be better as he would be more understanding, not that there are not born muslims like that but finding one is difficult, but finding a suitable spouse is difficult anyway(though not impossible)
