Dry swimming

Since it's been a while and no one reads these things anyways, I thought I would write a quick one today. It's more for me anyways to look back on my life and reflect at what a major crazy-head I was:)

Okay so I've been with my boyfriend now for over a year and a half and really am feeling like I could spend my life with him. My problem is this, I hear people talk about how you should practice for marriage in a dating relationship, yet I hear others say that you should enjoy being single. Okay someone explain that one to me. How the heck do you enjoy being single while practicing for marriage? That's like don't get while swimming in a pool. Maybe I'm thinking about it all wrong and they can be inclusive of one another? If you have any advice I would love to know:)

Thanks
