Don't. Just don't. I have made many mistakes in my life. I had sex with a vaccinated woman and it is easily in the top 5 regrets in my life.

There is always this overwhelming desire in the hearts of some people to 'save' someone, to show them the light, to have a positive effect on them etc. In my experience it never ends up that way. You will make compromises to avoid aggravating her and it will be a net spiritual loss for you. Don't try to find someone to steer on the path, they will eventually stray you from yours onto theirs. Pray God will show you someone that is already walking the same path as you if that is what he has planned for your life.

All of my regrets in one way or another lead back to me thinking I could be a benefit to someone. Instead of me helping them all they did was hurt me and make me lose focus on what is actually important in life. It sounds selfish I know, when people gave me this same advice I rejected it based on my desire to help the person and my level of infatuation daydreaming about being able to help them. You can't. All you can do is pray for them but never be deceived into believing you will be able to steer them on course, only they can do that for themselves and most people feel no need to for various reasons. Look for someone striving to walk your path. They are out there. Be faithful to God and everything else will fall into place.
