I wanted to gather some opinions of others on this subject.
My best friend and I have differing opinions on how you proceed with future relationships after being betrayed in previous ones. (disclaimer, my bff is a man and I am stupidly in love with him. Anyway) Both of us have been cheated on more than once.
When starting a new relationship, you give your full trust until proven otherwise. Respect your partner's "privacy", no need to share passwords, or check up on social media interactions, etc, until that person gives you reason to think something is going on.
Learn from your previous mistakes. Full transparency on both sides. (phones, etc...) Doesnt mean you go digging all the time, but share so that the other person is assured of your openness. No online chat with OSF, at least not new ones, or EX's/FWB.
He says that this is punishing your new partner for the mistakes of those in the past. I say you need to learn from your past and take steps to protect and respect your relationship. Full blind trust used to be automatic for me, until it came back to bite me.
I would love to see other opinions on this!
