Welcome to the board!
After being raised a JW, I also believed that they were the most morally upright people and "the world" was filled with those who were untrustworthy, immoral and the like. It didn't take long to realize that was just one more WT lie designed to attract and retain members in the organization. Not only does the WT not have a monopoly on morality, I believe JWs are even more likely to commit adultery. In the WT there is only one way to "break" a marriage and that is adultery. I have known JWs who commited adultery just so they could end their marriage.
It may be an enlightening experience for you to develop friendships with people who are not JWs. I'm not talking about single women who you might get involved with. I mean people in general. As you get to know them and realize they are good people, you may develop a new confidence in future romantic possibilities.
Best wishes to you.
