Maybe you don't feel good in your relationship anymore. Not something wrong with you personally. Ppl change in a marriage, and then after years go by it's like you don't know your partner anymore, not how he/she used to be. Lots of couples go through that, it's up to you two to do something about it together, or decide it's better to break up, that's entirely up to you both!
Pls let me know when you have posted details. I can't relax around my partner either and I am very interested in your story/question.
Who (if anyone) from your past does he remind you of?
I understand that when one can't relax around another person, a decision to relax doesn't work. Something else is going on and needs to be addressed. I'll respond to your question about why I can't relax around my partner in a message.
you dint leave any details
