I have one BFF-she and I can talk and gripe and let each other know we are there for each other.
When I am being a witch(with a b) she tells me to knock it off. She listens when I'm down and celebrates when I do something I am proud of. She let's me know when I have given too much of myself and when I am being an orge. I do the same for her.
She is the sister of my heart and I trust her more than I do my family.
My other BF is my husband. We connect on another plane all together. The trust, caring and honesty is there as well.
Honesty, trust, caring is the basis of my relationships. And that is why both have lasted as long as they have, thru overseas posts and oceans separating us.
