Love is BS and it's fleeting.
You lose your hair? The love is gone.
She meets a better man than you? The love is gone.
You fart in the bedroom? Well, you get my point.
Women will say they love you, and then the next day, they'll be like: "Sorry, my feelings for you just changed, oh you actually invested years of my life in me and hoped to start a family? Sorry, I just don't love you anymore, for no reason, now kindly f*** off while I replace you and repeat the process."
It doesn't matter if a man is in love or not. Women call the shots, they decide if the relationship continues or not.
