Been there. Get on with your life and you will forget, but learn from it. Don’t go all in with your feelings for a girl you barely know or for any girl for that matter. You might find it hard to believe but that is not the kind of dynamic you want. Some guys are notorious for this; I was one of those guys myself. To start it is a huge turnoff for a girl to know a guy is so hopelessly attracted to her and you might even lose a girl just on that. But think for a second what will happen if you do get in a relationship; who will have the power? It will be you who has to make all the concessions and you who has to work to make her stay, and you who experiences the agonizing fear that she might leave you. Remember that you should always be able to walk away from any relationship, no matter how deep, if things aren’t in your favour. You can and you should want the girl, but you should never need her. Your goal should not be to possess girls but to enjoy them, even in a relationship.
