Your fixed nature means that it could take a while before you find just the right partner, and there's nothing wrong with that!
And your loyalty and devotion indicate that you'll stick with your choice once you make it (although there are times when it would be better to let go).
Potential partners should be open and understanding enough to know that it will take time for you to get to know, trust, and depend on them.
If they're serious, (and you're so amusing and fascinating, why wouldn't they be?), they'll persist. Just look at the fabulous prize they'll win for their effort (you)!
