please don't, you know where the path end

is it possible to have "friends" while you already have a relationship? how do you define friendship? what are the limits? how do you know that your friendship doesnt change to affection; as friend do know you better, doesnt give you headache and doesnt expect anything from you? they will accept you just as you are now; for, they doesnt have right to ask you to change for them. because they are not the ones that you will live with most of your life. is it really worthy if you want to jeopardize a long built relationship so you can make some new friends while you are aware that there are chances that you will rock your relationship? so, you can add limits to your friendship. but are the limits clear enough? there are times that the border is so blurry, so messed up that you will have to make decision. how do you set the limit? can do you measure friendship? what??? am i jealous? hell, im jealous. because i've been there. and you dont want to know what it did to my life.
