I think that the fear of falling in love stems from one's own fears and insecurities, something that I myself am familiar with. For me, this can tie into the whole negative self-talk where I'm not good enough for someone. But I've realized that if I set conditions upon myself to be deserving or worthy of love, then I also risk imposing conditions on others, even if I'm unaware of it and it's not my intention. In relationships, these conditions can manifest themselves in subtle ways that can be detrimental to the health of the couple.
Often times, many of us are stuck thinking about ourselves and our own shortcomings and issues. It's always about "me" or the "I" that seeks to possess, to claim, to call someone mine. Chances are, if we keep contemplating our fears and all the "what if's", then things will fail. Fears, insecurities, and uncertainties reflect a love that's about us. It's a love based on conditions.
Love--true love--is pure, timeless, and unconditional. It doesn't seek to possess nor does it discriminate. Moreover, the intrinsic value of love extends beyond the realm of romantic love that we carry for the one special individual; it extends towards others and towards humanity at large. So, what if we shifted our thoughts towards others? What if we simply made it about the other person and everything that we truly appreciate and love about them?
That's why I'm learning to focus on the present when I'm with someone I love, and to make the best of each moment we spend together, as if it would be our last. Never mind the what if's. Sure, risks are involved and my heart is left in the open for wounding, but I don't know what would kill me more: having been vulnerable and hurt, or not having opened my heart at all, hiding it safely from the world, only for it to be turned into stone.
On another note, life's just that: life. Things will hurt and the person you love will fail you. But in my eyes, nothing's more beautiful than people who've lived. Nothing's more beautiful than those who've been whipped to and fro by the wind and on the brink of death, but have managed to resurface alive and untainted. Your life experiences make you, you. Beautiful just the way you are, and nothing less.
So, what the heck, take a leap. Carpe Diem.
