So forgive me for posting these interviews of prostitutes. I am only doing it to illustrate a point. At the 20:15 min mark she describes how she once had a man that truly loved her. He used to take care of her and tell her she is beautiful. She then said how she tried to destroy him because of it. She states that she treated him just like the abusive pimps treated her.
This is what we need to understand. You can not love a girl that does not love herself. Most girls do not love themselves. Most of them have severe self esteem issues. They will punish you for treating them well. This goes for any relationship male or female. Self love is the most crucial component to having functional connections with others.
If you are pursuing a girl too much she will think something is wrong with you. This is because she does not feel worthy of special treatment. They only want special treatment from certain guys that they think are hot.
The only girls that really accept love are the ones that come from perfectly functional families. They had a father that actually made them feel worthy of respect. Dating these girls is relatively easy. Their hypergamic requirements are within reason. They actually respond positively to romance without overthinking it.
Most girls these days have low self esteem. Low self esteem people will never be able to appreciate love. Just move on.
