Trust issues are yours. I trusted my STBXAH so completely and for far longer than I ought to have. I ignored warning flags. I chose to continue to trust him in my deep denial. I'm learning that I have a choice in how much trust I give anyone - it isn't all or nothing. I have to judge by someone's behaviour if they're trustworthy enough for me to trust them - does that make sense? When and where I trust is all about me - it's my power! If you find you cannot trust someone because you have recognised something untrustworthy in them, then it is all yours - your judgement, your power and your responsibility. I don't think you can be 'made' to trust someone.
Are you asking this because you want to say to your AH that you don't trust him so he has to do something about it and change? Is he demanding that you trust him? Can you give a bit more detail?
