Actually, I think it's the opposite: it's you that's being forced by yourself to be with her. I mean, she ain't gonna be existing in this world anytime, yet we are forcing ourselves to be with them.
Yes, we are forcing our love onto them but in such a way that we get the aggravation instead because they're not gonna notice us. Ever.
But here's the question: Are you ready, as a person in love, to endure all these things, for her? Can you live with the fact that you vowed only to love her, even though she can't actually love you back?
If you can, you've made your choice and I hope you live with it.
