Dear Em & Lo,

I’m 18 years old and I’ve been with my boyfriend for 3 years now, since I was 15. It’s been great over these few years. We’ve argued but everyone argues and we’ve managed to work things out and talk on a level where we can understand each other. He’s most definitely my best friend and when he talks to me I feel as though I am everything to him also. Recently he  asked me to become his fiancee and to move in with him. He made it very clear that it is not to pressure me into marriage, I can do that whenever I am ready, etc. But he loves me and wants to take it to the next level. Sounds like a fairytale, right? But the problem is he’s the only serious relationship I’ve ever had and many people have told me to not rush into anything, to date more guys and hang around before settling down. Should I risk losing someone that I love and can manage with just because I am young and in experienced?
