Q: I have been in a healthy, fun relationship with my boyfriend for the last 14 months. We love each other a lot and there's a lot of chemistry. He often talks about how he wants this relationship to end in marriage, as do I! The only problem is that I have never been completely sure and I often worry about this. I've heard many times 'when you know, you know.' I know that one needs to be really sure before buying the ring etc.
