I don't agree with MrMan. He said he would feel angry/defensive if his partner asked to look through his phone. He tried to support this by asking if we'd be happy for our partners to look through our stuff.
I said yes, I would be okay with that, and was okay with it when my X asked the same thing. While I expected him to trust me & respect my privacy, I never hid anything from him.
About reading the postcards: It honestly never crossed my mind to read his, even though it would be easy. XH couldn't believe I hadn't read them! That should have told me his idea of privacy was more like secrecy, not respect.
But those differences could have easily been worked out, if we'd had equal respect and concern for one another. The problem was that I felt insecure and he made it worse by calling me paranoid, intrusive, etc, etc.
If he cared about me, he would have been upset I felt like that, wouldn't he? He would have done whatever he could to help me feel safer in our marriage.
He didn't. He took more care to hide stuff, and told me I was being unreasonable. He was cheating. But I didn't find out until the marriage was already over.
I'm sorry my post was unclear!
Look, if you asked me something and I replied angrily - saying you were bonkers and didn't know your own mind - you wouldn't trust me, would you? You'd probably feel quite upset, annoyed and a bit thrown by it all. I'm just a stranger on the internet, and you know you should expect some consideration from me.
I think you should be able to expect more than that from your partner :(
