Re: GF not telling her friends she's dating me...
I hate to admit this, but I have been through this. A few months back in fact. Now she did tell most people about me, but one or two she didn't which bugged me.
Think about it, what would prompt you to not tell your friends about this girl? Get inside her head. I mean, if you guys split then she avoids embarrassment from her peers since she never told them. Right? Not a good position to be in.
The quick answer for me is that she's simply not ready. Even if she thinks she is. A new relationship is usually flaunted about. Not kept in secret.
I know that your ego will want to correct this without losing her, but I'm telling you that you are sparing yourself a lot of heartbreak down the road if you end it now. And I'm not a advocate of walking away. In fact, I'm big on working things out. But you are an alpha man with standards. If she can't do something as simple as acknowledge to everyone that she is taken then you would be settling and she isn't for you. Let her know that you will be there when she is ready, but that you don't want a halfass relationship. Put your ego aside and find a woman who would BRAG to her friends, family, and even exes that she is with you. You don't need that ish.
