I'm finally going to confess ...
What are you going to confess?
I'm ready to spend the rest of my life with you
It's okay to confess your feelings when you have the right outlet to do so. However, you should be sure that the person you are confessing to is able to reciprocate your feelings. If not, you risk feeling hurt and rejected.
Well, I just need someone to say that they love me back.
I think that you should make sure that the words you are saying are true. You should at least know the person that you are confessing your feelings to.
