There are different kinds of rejections. What happens many times is, that many rejections are not true rejection. For example, at the time you interact with her her mind is somewhere else. Maybe she has a BF, maybe she is not thinking about serious dating at that particular time, maybe you don't look attractive enough at the moment. There are hundred of other reasons, but basically she doesn't really reject you. She just puts you "aside" as she is focusing on something/somebody else.
Now, after several days or months, she MAY change her mind. I can tell you, this happens even after YEARS. She remembers the guy who liked her a lot. She is thinking where is he, what is he doing, how would it be to date him and so on. You might actually get quite good changes, much better than with a new girl as she may be chasing you now. So just because she doesn't accept you today as a BF or lover it doesn't mean that she won't in 3 months or 3 years from now. When a girl rejects you I wouldn't really jump into any conclusions. I wouldn't determine anything, I wouldn't make any black lists, I wouldn't make any conclusions - I would just leave it "open". Try to adapt the attitude "who cares".
Try not to have those "rejections" effect you negatively, that would tell her that you are immature guy. Don't get upset or insulted, don't get down on yourself. Learn to be NON-REACTIVE, just walk away from her with a smile, and then next time you see her hit on her again as if nothing happened. Watch her mind change in front of your eyes!
It is actually a very good strategy to get girls. You hit on her and you disappear. You hit on her again, then disappear again. She WILL remember you as a guy who likes her a lot, and next time you meet her she may actually show quite a high interest in you. Why wouldn't she? If she is a normal person, she will always like those who like her. If she is a bitch, well, good luck trying to fix her.
You also need to keep your frame. Your frame is always that you want to have sex with that girl you like. When you meet her for the first time, you want sex. That is it, no negotiations, no friendship, no orbital zone. You get rejected, well, it is ok, no big deal, you walk away with smile. You meet her second time, and you want exactly the same - sex. Imagine that you meet her for the first time and you want sex. She rejects you, but then, but 3 months later she changes her mind about you. She meets you again with HIGH interest in you, and she EXPECT you to have the same frame. Her mind is ready for that frame - but now you changed your frame and present yourself as her "friend". She will be disappointed. Don't do that, never change your frame, or she will walk away...
As far as "honor" and "pride", it depends what you mean by that, and it would be a long topic without clear conclusions anyway. IMO it is much better to talk about self-esteem, value and maturity instead. A guy should believe that his value is higher than her value. It doesn't have to be too much, but it should always be just "above" hers. If your value and self-esteem are high enough, you won't really get hurt by her rejection. It is her loss, not yours. If you put her on a pedestal, you place her value above yours and you gave up your self-esteem. Put yourself on that pedestal instead, make your value and self-esteem above hers. From this point of view, if she doesn't want to move things forward with you she simply doesn't meet YOUR standards. You walk away from her because she is not good enough for you - and not the other way...
Learn to deal with rejections differently. For example:
(1) She may reject you but you had balls to go after her regardless you knew well that there is always the possibility of being rejected. That is very good, average guy can't do that, so you should celebrate it. It takes lots of balls to go after a girl while knowing that she may reject you. (2) Rejection is not a failure, it is a forward progress. You are moving forward, you are moving to another girl, and by going after this girl you learned a lot of skills. You can use these skills with another girls. (3) Learn not to take the rejections too seriously. Look at them as a future investment as she MAY change her mind. It is like as if you put a seed in the ground, and now all you have to do is wait if something will grow out of it in the future. Sometimes it does. (4) When you meet a girl, DON'T EXPECT ANYTHING at first. You just want to talk, see what kind of person she is, what she likes and does, who are her friends. See if there is any vibes or not (you will just feel it). See if she wants to go for a date. If yes good, only now your skills should kick in. If not, ok, no big deal, just walk away. Nothing happened. Try next time. (5) Another good way to deal with rejection is of course Abundance Mentality. Talk to different girls, meet different girls, date different girls.
This way you will become more independent of one particular girl, you will become more experienced and knowledgeable, you will be less clingy and needy, your value will naturally grow - you will simply become more mature. Each rejection is actually an excellent opportunity to move forward, you are not "stuck" with one girl but you are moving forward...
