Boy meets girl. Boy falls for girl. Girl falls for a different boy. Boy 1 stands by her side regardless. Unrequited love sounds cliche but oh gosh does it happen way to often in real life for it not to hit you in the gut when you hear someone's love story gone wrong. But no matter what the outcome; it will end up alright.  

Time can heal a lot but if love is meant to happen it will and if it's meant to fail it will as well. We can't force a situation but let fate happen as it's destined to be and live life moment by moment.
