You have a few options.
1. Friend her on facebook - talk t her but don't talk too long or you end up in the friend zone.
2. Rock up to her Church in a black suit, with a hat and sunglasses and start dancing and singing you have seen the light.
3. Ask her out.
4. Since your mum was trying to recommend her clearly her parents might have had a similar idea. Get them to arrange a marriage for you.
