Sometimes, I feel exactly the same way. It really does hurt alot when you love someone and they do do not respond. I always thought that I could not live without a man, so I put up with that b.s for so many years.
Thank God, has helped me to realize that I have to love myself first. I still struggle with that, since my self esteem is still low. You are lovable, sometimes it takes an incident to realize it. I am sending you a bunch of hugs.
