Answer
As-Salam `Alaykum Brother,
You are asking very good and relevant questions. You can’t generalize about women, whether they are wearing hijab or not. Some women who wear hijab do so consciously and for the purpose of pleasing Allah (swt). Such a woman, who made this choice, is probably less likely to have an affair because her mental condition and spiritual condition is more healthy and sincere. However, just because a woman wears hijab, that does not mean she has sincere character. If she is wearing it solely to comply with cultural norms, then who knows?
To find a good woman who will be loyal and devoted to you and the marriage, seek for a woman who has a good reputation in her community for doing good works, who keeps herself busy with healthy activities, and who can be found by her peers easily.
If a woman can be found by her family and friends, if people know where she is and what she is doing, then she probably isn’t sleeping around with men unmarried. This will increase the probability that you are finding a good and obedient woman. Marry a mature woman who understands the responsibilities of marriage and is ready to make a commitment to marriage.
Allah (swt) will judge women too; women have a responsibility to be good to their husbands and faithful in their marriage. Look for a woman who understands this and who sincerely wants to please you and Allah (swt). Indeed, if a woman pleases her husband, then Allah (swt) will be pleased with her.
Hope my answer helps,
