As others have said, live a full and happy life.
From a practical perspective, make a list of skills that you think would help your family when you are a wife and mother. For example:
–Cook healthy, balanced, nutritious meals
–Budget. There are more fights, I think, over money than over anything else.
–Communicate. Read books on communication. Watch other people talk to people with whom they’re in relationships and see what you think works and what doesn’t, then emulate the good stuff.
–The basics of NFP. Even if you don’t plan on using it immediately or ever, it’s a fantastic tool to have from both a women’s health perspective and from a marriage perspective. Learning NFP while you aren’t having sex is a lot easier than when you are, and that goes double for if you’re married, postpartum, have been told very sternly by a doctor NOT to have another baby for at least another year, are dealing with a newborn/sleep deprivation/perhaps PPD–oh, and now you’re supposed to ascertain what this type of cervical mucus means 5+ times a day on top of all that to determine if you can or can’t have sex with your spouse? Ugh. Not fun. Postpartum NFP is harder and less clear than non-postpartum, but having the basics down will make it a lot easier than trying to learn it while under serious stress.
–Learn to decorate a home so that it’s both beautiful and functional–and don’t forget safe for kiddoes! Look at pictures online, on Pinterest etc, and figure out what your “style” is and how to achieve it without breaking the bank
–Clean both well (ie, keeping germs and clutter to a reasonable minimum) and efficiently. One of the hardest things for me to learn as a new mom was how to keep the house looking nice without spending every second of DD’s naptime cleaning frantically. It’s a lot easier to clean when you have all day with no distractions to tidy, dust, sweep, vacuum, mop, etc.
–If you don’t have a degree or a skill set that will enable you to support yourself, get one. If you do, then improve via continuing ed and keep your licensure/certification up to date if applicable. Sure, it will be awesome if Mr. Right comes along and you can be a SAHM, but there’s no guarantee of it. Even if he does, he might get sick or lose his job or, God forbid, die sometime and leave you with small kids to support. Having that degree can mean the difference between maintaining a comfortable home during a scary and stressful time and moving into a rent-assisted apartment while on welfare. Hope for the best, plan for the worst.
–Teach yourself basic home repairs. Unless you’re especially inclined to it, there’s no reason you need to know how to remodel a kitchen or replace a roof, but understanding how to replace a toilet valve can means spending $20 on parts rather than $500 on a plumber. Youtube has thousands of very good how-to videos on home and auto repair.
This is not a complete list, but it’s a start.
Insofar as finding Mr. Right, you might consider moving to a bigger city with a more vibrant Catholic community and/or getting on Catholic singles’ websites. DH and I met online on one such, so I might be a bit biased there

. Still, provided you both use common sense, it is another venue in which to meet potential future spouses.
