Friends - someone who knows u, n you know them, you are comfortable being who you are with them, n you are having to be yourself around them nothing more nothing less.
One of the more pure relationships
Outside of birth that exist, hard to get good friends if you have good friends you are lucky indeed cherish it, nurture it, keep it going
Do not let your partner / husband
Ruin it, he / she is just jealous if you want to be happy you got to have friends or you will be depressed and lead a sad life on all fronts,
Choose your friends carefully; once you are friends be there for them.
