What's with those that chase after members of the opposite sex that are obviously with somebody currently?  I've never understood this.  The saying "there's still plenty of fish in the sea" is thrown around a lot, but there's still those that choose to go after the fish that are already caught, and in somebody's boat.  This is the cause for a lot of violence that goes on within genders, because pursuing another person's guy/girl is a blatant show of disrespect towards them. 

You must respect their boundaries, and the relationship that the two have created over time.  If you choose to ignore this, then you must face the consequences that come from the opposite side of the bond finding out.  I'm not a violent person, but I look at matters of the heart as being sacred territory that nobody besides the individual should tread on.  It's like when somebody trespasses on private property, ignoring the "No Trespassing" signs all around, and they get shot or prosecuted as a result.  That's how it is with romantic relationships.  It's private property.  A trespasser creates dissent between the two people in the relationship, and jealously tears their bond to pieces. 

Many people can say that they're not the jealous type, but EVERYONE is the jealous type.  Everybody has that protective instinct that comes out their ability to retain something they care about is compromised.  The guys that have made the mistake of sweet talking my past significant others learned the hard way that it's not the right thing to do.  This needs to stop though.  It's another roadblock on the path to peace between the two genders.  Guys can't be trusted for the most part.  If they've got the opportunity, they'll screw over their own if they can.  I'd never do such a thing however, because I respect the bond that's created between two people in a romantic relationship.  So don't try to snatch up somebody else's significant other.  GET YOUR OWN!!!

The person that's trying to move in on such a situation only carries half the blame though.  It's the responsibility of the guy/girl trying to be coerced to reject these advances.
