A friend's daughter is getting married in September to a man she met on CatholicMatch. In our chapel there are also very few eligible singles because once they go away for college or move out of their parents' home, they quit practicing the Faith. The few singles remaining tend to be in their mid-30s and older. There are two single women in their late 20s, both with children out of wedlock, a few single men in the same situation, paying child support, widows, widowers, and four singles who are mentally/physically challenged.
I'd suggest CatholicMatch, but be sure you court in person for at least 8-12 months. That may entail you having to move. Meet her family, go to Mass together. Certainly get counsel from a good priest before doing anything requiring a major commitment. My friend's daughter's fiance moved from across the country and has a secure job, a condo, and both are mature.
Most of all, pray not only for a wife, but for the wife who is already known to Our Lord.
