Having a girl who loves you (and whom you presumably also love) is a great advantage for a man. It gives him confidence, it removes the enormous cognitive load he would otherwise spend checking out or pursuing other women (in particular: wondering whether a girl he likes also likes him), it makes him look good in front of other people, and generally confers all sorts of advantages in life.
Therefore you shouldpress your advantage now. You are now ahead of the game (even if only temporarily) and the strategic thing to do in a situation like this is to use your position to lengthen this advantage as much as possible.
Practically speaking, this means two big things:
1) Secure and improve your current position
Because you are currently the one with this girl, you have an inherent defensive advantage against any invaders. Therefore, you must fortify your position by upgrading it and familiarizing yourself with the terrain so that you can defend effectively if/when it ever becomes necessary:
Be a good boyfriend. Be funny, entertaining, attentive, and emotionally open. Don't be needy, supplicating, or spineless. Women (people) value an emotionally powerful connection with a confident, emotionally rich person. Be that person, because the unfamiliarity of a new suitor (even a handsome or rich one) will not easily overcome this.
Don't be afraid to have fights, but seek to use them as an opportunity to learn things about how you or your girlfriend act when under stress, and build a deeper understanding between the two of you. She will know that she'll have to start all over again to reach this emotional depth with a new man if she leaves you, and will be reluctant to do so.
2) Lengthen your advantage
While you have a girlfriend, you have an operating advantage against other men, i.e. your increased confidence, mental stability, and lack of mate-pursuit overhead allows you to do more work faster and more effectively. Use this to get further ahead. Do the following things:
*.Work out, to improve your body.
*.Improve your hygiene.
*.Improve your wardrobe. If you have no fashion sense, ask your girlfriend to go shopping with you. Girls love this; it makes her man look better, which makes her look better in front of her friends when she shows you off.
*.Work on becoming richer. Every man has a different way of doing this, but key to all of it is loving your work and being able to focus on it so that you do well, which is something that the love of a good woman greatly helps with. You don't need to date anymore, you just go home from work and hang out with your girl. This is time saved, and time is money.
All of these things will makeyoumore handsome and richer,fasterthan an equivalent guy withnogirlfriend. You don't know how handsome/rich a new guy that she meets is going to be, but you can improve the probability that he will belesshandsome and/orlessrich than you specifically. This, combined with an ever-deepening emotional connection between you and your girl should give you a superior tactical advantage against almost any would-be suitor.
Also: get good at figuring out what she likes in bed, and keep working on making that better and better. Much of that is practice and exploration. You shouldn't need this advice to encourage you to get practice. If shedoesleave you, you want to have left a psychological "poison pill" in place where she thinks about you while she's having sex with the other guy or, ideally, compares him unfavorably to you. If so, he will unconsciously pick up on this (or consciously, if she's foolish enough to mention it), this will make him very insecure, which will contribute to the self-destruction of that relationship and cause her to come crawling back (if you want to take her back).
