It takes two people to tango. If you have expressed all your feelings to her and she still doesn't feel the same way about you, it is time to let her be. Give her some space to clear her mind and think. If the outcome is the same, you should let go. Love is attraction that comes from deep inside you. Perhaps she doesn't have such feelings for you. You can't force it and some things are never meant to be. When the stars finally align in your favour, you'll have your one true love. It could be the same woman or somebody else. Don't sweat it. Pushing harder will only make her to further move away from you. It may irritate her and put her off. Even if you love her, like a bed in a cage, set her free. If it finds a home in you arms It will surely comeback. If not, move on.
