Should I tell my boyfriend I love him?

Welcome to Fluther.
Only he can say if it will “freak him out.”
Life is short. I say go for it.
People on here advised me to tell an old friend this summer that I had feelings for him, and I am very glad I did so.

Well… If you do… then why not?

Show him you love him instead. The words can come later.

Show him? How would I do that?

If you feel it and you need to tell him, why not?

There is nothing worse than to never seize the moment. When that moment is gone, it is gone and remains so. You live once and whether or not you make a mistake, you can never tell if it is a mistake until it has been made.
I don’t believe that it would do you any favors to keep this sort of thing to yourself for too long. Tell him!

Tell him the next time you see him face to face. But please don’t wait for him to say anything of any sort back to you! He may be emotionally bumfuzzled and not know how to respond or even be in touch with his feelings well enough to say anything.

Just say it, kiss him, and then smile and hug him.

If it freaks him out, then you have badly misjudged the relationship. You need to be true to yourself, at least in matters of the heart, and if you lose him, better sooner than later.

Personally, I cannot resist telling someone I love them as soon as I start feeling it. On occasion, it may have freaked her out, but like I say, better to be clear what I want and lose it now, than to hint and play the game and find out later. I don’t really want to win someone by playing them. I only want someone who wants me for me. If they can’t accept me as I am, I want to know soon.
