Most Helpful Guy
First off, confessing is embarrassing, yes. It's you bearing out your feelings so of course it is. Weak? No, if anything it's brave because you're making yourself vulnerable and taking that chance. It's scary, and understandably.
If you really like the guy then I say tell him. It's better to try than to let him get away without ever knowing if things could have worked. If it works great. If it doesn't, sure it'll hurt, but you'll recover and feel better in the long run. And then you can move on and find your next love interest later in life.
Also P.S.: Getting confessed to in my opinion is adorable and wonderful.3THIS IS NOT RELEVANT ANYMORE
