Love is a commitment. Not an emotion. Most of us think that we are in love when really we are just infatuated with someone, strongly attracted to them and want to be around them all the time. When you love someone then you just know it in your heart! :)
When every time you look at her, your heart stops. Because to you she's that breathtaking. Every time you kiss, your whole body flutters and your heart beats so fast. When you can't spare to be apart. When she's the only girl you notice out of a hundred girls in one room. When you hate other guys staring at her, even if its in a friendly way. -sappy things.
Well romantic love is not a feeling, but rather a decision. A decision to spend the rest if your life showing someone everyday how much they mean to you, and having those actions reciprocated. It's knowing that even at that persons worst they still bring out your best. It's knowing that person front to back, and embracing their flaws as much as you embrace their strengths. It's having a base foundation to build a healthy relationship upon. A foundation that was built and is maintained at all times by both parties involved. A foundation comprised of trust, communication, compromise, commitment, and mutual attraction. Without anyone of these a relationship can crumble and the decision to love begins to deteriorate. But if you both decide to truly love one another; you will both spend the rest of your lives working hard to maintain that foundation. You can hang all the bs "feelings" on it you want, but that's what love really is.
