What happens in your relationship, remains in your relationship

I'm gonna keep it 100 ya'll, 80% of the time, relationships fall apart cuz people wanna put other people in your business. Let me just say this from personal experience. I've seen my relationship slowly drift and fall apart because of that. (Not the one I'm in now) On a real note, when you allow people in ya relationship it makes things complicated between you and your partner. A relationship is described as two people, emotionally, physically, and mentally with one another. Keywords: two people. Not 3,4,5,6. Thats where you go wrong. 9 out of 10 times when you talking to someone bout relationship problems its mostly the opposite sex you talking to. Men have a female friend they talk to and women have a male friend they talk to. But there is the fault. You allowing someone space to see whats the problem so they can either watch you fail, or find a way to get you from your partner. Thats what you call venerability. We all know bout that and men are mostly known for using it. On that note I'm leaving it at this, if you know what best, please take this advice!
