Dear Katrine,

I think your main message should be about yourself: that you like him but you haven’t always shown it because you get anxious around the people you like. You don’t have to say it in one breath and admit that you like him immediately, but you can pace it a little. I like your idea to start with explaining your own behavior and apologizing for it:

I was thinking about apologizing for my behaviour and say when my anxiety kicks in i become rude without knowing (shut ting down, ignoring people) and it’s hard for me to keep a conversation going(he had to constanly be the conversation starter) and then tell him i apreciate him taking time meeting me and give a yoga session

So you acknowledge that you behaved a little strangely and you explain why. If you want, you can also apologize for when you left the pub without saying goodbye. That would be a great prelude into saying that you did it because you like him, and seeing him talk with another girl made you really anxious, so anxious that you felt you had to leave immediately. And then I’d watch his reaction…

I would leave out this part:

then maybe something like but I don’t believe you didn’t read any intention into this, I think you like me as much as I like you. You had several chanses to cancel but didn’t you could have left soon after the session but you stayed.

I wouldn’t argue with him, or present “evidence” that he likes you. It’s on him to tell you that. I mean, you can say that you’ve read some of his behavior as having a thing for you, but you shouldn’t claim it as evidence that he really does. If he still resists and doesn’t want to admit that he likes you as a girlfriend, then there is no point in pushing. If he likes you, he should admit it as soon as you admit it to him… If he needs convincing and is reluctant – after you’ve confessed what you feel about him – then I don’t think you should argue and push any further. But I hope it won’t come to that!

So in summary, this is what I’d suggest: express your side of the story and your feelings, don’t assume his feelings. And watch his reaction… I hope it will be a positive one!
