I understand what you're saying but
Why is this a 'but'? You go on to confirm that you are being interpreted wrongly. Communication is a 2 way thing: when it goes wrong, it isn't one person's 'fault', it's just like having a bad line on the phone. The only exception to this is if someone is being deliberately unpleasant, and giving what you say hurtful meanings.
Either way, if you're trying to say good things and the other person is interpreting bad things or unhelpful things, in a consistent way, from your words, it's an unhealthy situation for you, and you are responsible for pulling you away from it.
The healthy approach here isn't 'He keeps misinterpreting me, so I must be saying it wrong', it's 'He keeps misinterpreting me so there's no point trying to communicate with him'
Why is it so important to you that he likes you? What if he doesn't like you? Can't you just let that be? Do you like you? Do you respect you? What you're demonstrating is that you need him to like you because you hold his opinion in very high esteem. Why is that? What's so special about him, that his judgment is so important to you? Is he some sort of qualified judge of characters that you highly respect?
