This is a very black and white statement where its either good or bad and there is no inbetween and most of all, there is nothing better than bad. I understand and know where you are coming from, because most guys when it really comes down to it, are from that planet. Most wants to date one of these lovely girls, but when they get it, they cant take the heat and loose out one way or another.
But there are more aspects, like stated above, if you love someone, you dont give a fuck about their status, it simply dosnt matter. However, insecurity is a personal flaw, not something that can be related to the better half, however, your better half can inflict insecurity on you, if you lack the conversations that will make both parties understand the situation. And i believe being open about stuff, getting to understand the girls way of thinking, reduces the guys she is seeing to moneybags for grabbing.. that is the psychology i try to use when i view things.. however, sometimes the good old brain kicks in with its logic, wich dosnt apply in this environment, because its not logic, it illogic and needs to be dealed with as such...
