The whole idea of love is scary - so is being with someone for the rest of your life and being happy with them for the rest of your life. There's lots of research to suggest that, actually, love's not really that simple.
To be honest, I tend to romanticize the past, and though I appreciate all the conveniences of modern life, sometimes I yearn for simpler times.
I'm an optimist - I feel like an amazing part of life is that at any moment.
