Clarry I do find your posts very strange. Clearly you have different boundaries in your relationship.
However, a recognition of fidelity, emotional and sexual, is not synonymous with being suffocating or emotionally controlling.
Very few people have a problem with their husbands 'looking at another woman', but I imagine lots have a problem with snogging. Just as I would have a problem with an emotional affair, cyber sex or texting.
The OP was asking, in our relationship, which side of the line it would be on. It has nothing to do with what our parents or neighbours think.
