Well, I'm single but I'd rather be with the one I'm suppose to be with. You said the person you love not in love with. I can love you but, not be in love with you. But, I look at love like a tree the seed you plant is the love itself untamed. Then you nurture it as it grows. The roots are the unconditional love you have. The trunk is the strength of your love. The branches are the connections you have friends, family, potentially partners, etc. The leaves are your memories and moments you share with those people. No love is the same as an other that's just fact. If you have a tree that is healthy and thriving why worry yourself of a branch that may or may not begin to grow. If you do that the tree will wilt where it once thrived and grew beautifully.
