I had read a number of threads here and notice one thing: no one giving advice to fight for love in case if one of the couple is not in love. Almost all advices is about to left this person alone and find another one. I'm not saying this is bad. But I'm interested why is this? Is it just an economy of the resources, 'cause finding another one is much simpler task than fighting for this one? Or is it because statistically there is very low chances to involve person in love if he\she is not interested in you?
For me it seems that humans are picking potential partners using some primitive animal instincts and there is no way to fight them if they decided that you are does not fit. So in this case there is only one thing to do - find someone whose instincts will approve you.
