clairey, I can understand why some people are confused by your situation ~ after all, you are asking about what he has said to you, then you go on to say you are just f**k buddies and you are happy with the situ.
Don't get me wrong (there's the saying again ;o) I am not having a go at you, but it DOES appear that either one or both of you has issues with the relationship. I once had this kind of relationship and the 'L' word never appeared in conversation...ever. You may be happy with the realtionship the way it is, but he may not be. This needs clarification, I reckon. x
