The key to a happy relationship depends on the length of the leash you have them on. A leash too short will keep them by your side but they will resent that and make them want to roam. A leash to long allows them to wander and puts a good deal of distance between you two. No leash gives u both a false sense of security that neither will stray but of course too much freedom is very tempting. So the answer is simple, don’t treat your significant other like a pet or a possession,don’t give them leashes or restrictions, don’t give them reasons to want to stray. Instead,treat them the way you would like to be treated…with respect, love and patience.
