Certainly not ! Being in love or attached with yourself will hinder you from making real connections with women. As for your friend, his self admiration is probably his way of coping with rejections and hurts. That's very sad.
Women like confident men who can make them feel secure and loved. Just be your nice, confident self. If you rely on the person you are dating to make you happy, you will only be disappointed. Why not be a friend also to whoever you are dating. This way, you get to know her better and connect better with her.The best relatonships that I know started from friendship.
I want to share with you a part of an article that I read -
" When we talk about love in this world, we are really talking about attraction and pleasure that are brought about by hormones. If we were to disconnect a person from his hormonal system, he wouldn't be able to feel "love." This again shows that what we usually think of as love is just an egoistic desire to enjoy. Sometimes this desire can even be cruel, desiring to receive fulfillment at the expense of another person."
