btw I wouldn't even say men give up on love fast, just with experiences you become smarter and not waste your time. When your young and a chick flakes you may give her another chance, when you feel her distancing you may "fight for her", you may do left and right to try and impress 
but as you gain experience you realize not to waste your time, if a chick flakes
, if she's distancing you know the end is coming and to eject, you don't fight for her because you realize if a woman wants to stay she will stay with you. As well you realize you don't need to do anything to impress her, if she doesn't like you for you nothing can change that.
Relationships and dating become easier as you get older. The he key to life is to always remind yourself that you only have control of yourself. I can control the women I want in my life, and I can also control to
if she is not bringing me happiness. Life and relationships is so simple when you think of it in that regard, if she is not adding to your life and if it's not seamless your wasting your time.
If she wants to be with you she will if she doesn't she won't.
If she wants to talk to you she will, if she doesn't she won't.
