You know i can answer 1 thing about this, i told my G/F she was the most beautiful girl in the world to me and i actually meant it, i still do, shes amazing to me. Now to your question, its just jealousy pure and simple, some people are worse then others, notice i didn't say women, some men can be just as bad.

I believe that she wants you to pay attention to her instead of a magazine. She is yours. She IS the most beautiful woman in the world and she wants to hear you say it and mean it. The models in the magazine are all just fantasy. Real women do not look that way usually. Your lady is reality. +5

Because you're dealing with very insecure women. As to your second question, the answer is yes;)

Of course you tell your woman that she's the most beautiful thing in the world. Sorry you feel it's a lie.

Just lie and say that although she (the model) is attractive, she's not your type and that your gf is just perfect. Trust me if she has confidence issues it'll help and try to compliment her daily.

Lie? As far as I know, the woman you are with and the woman you are in love with, should be the most beautiful woman in the world for you.

I take it you've never read Sonnet 138: When my love swears that she is made of truth, I do believe her, though I know she lies, That she might think me some untutored youth, Unlearned in the world's false subtleties. Thus vainly thinking that she thinks me young, Although she knows my days are past the best, Simply I credit her false-speaking tongue, On both sides thus is simple truth suppressed: But wherefore says she not she is unjust? And wherefore say not I that I am old? O love's best habit is in seeming trust, And age in love, loves not to have years told. Therefore I lie with her, and she with me, In summary, yes, women (and men) do like to be flattered by benevolent lies like, "You're the most beautiful woman in the world." Would you really like to hear your girlfriend/wife gush about David Duchovny? Hopefully, it would only be a partial lie, because you should think that your partner is beautiful. Women are very sensitive about their attractiveness relative to other women because women experience more pressure than men do to be good-looking. So be nice, and remember that the truth doesn't always need to be told. Even if you think that a woman in a magazine is beautiful, there's no reason to announce that to your SO. If she asks how you feel about a celebrity or random woman on the street, simply say, "That girl looks nice, but she's not my type."

Don't mix truth with women. The don't like telling it, and they don't like hearing it. You should always lie to them.

maybe you should just keep your comments to yourself when you're in the company of your girlfriend and feel the need to compliment another woman... I don't think any woman would be all that thrilled to hear their man say that another woman is beautiful. We are well aware of the fact that there will always be women more beautiful then ourselves. BUT if I were her I would probaby say.. yeah she is pretty and move on; that's what a secure girlfriend would do.

I don't mind the truth, but He needs to say something about how wonderful I am too. +5

yes, they want you to lie.

While women tend to be emotional (men are visual), they seem to think that LOOKS are everything. Thus the makeup market, the diet market, the clothing market, etc. So, when a guy sees a good-looking girl, better makeup, better dressed, even maybe better-looking than her, she feels threatened. The major difference between seeing a woman in a magazine (or elsewhere), and being in love with someone is that you have NO CLUE what that woman in the mag is like, but you DO know (at least a lot more) the one you love. That knowledge, along with her looks which is probably what drew you to her in the first place, should be enough for you to honestly say that she is more beautiful than anyone, making it NOT a lie. HOWEVER, let's go a different way. My ex was a BBW. 6' tall, and ... not small. She would, periodically, point out a very heavy woman on the street, and ask if she looked as heavy as that woman. 99% of the time, I could very honestly say "no". Her height helped in that matter. But there was a small percentage of the time I had to either tell a white lie - "No... No way" - or that I didn't see the woman, or would have to say the truth so it mollified her... "Not in the same way". I knew if I'd answered a "yes", that it would devastate her, because I knew her. Remember that the vast majority of women who would ask this type of question flat out are insecure in their own beauty to others, especially you. So, consider the consequences, and make your mind realize that you DO believe your s/o is the best-looking woman out there, no matter what she looks like, her shape, size, whatever. And realize that she's insecure in her looks, so if you were to say "yes" it could/would hurt her. Try not to "lie", but couch the truth so it's easier for her to take. ;-)
