It is good and it is not. If you love her and she loves you, and you are together, it's all good. You can have little whoas running around and be happy republicans till the end of your lives. Love and sex are the highest feelings we humans can experience. Makes you wonder why people believe in heavens where God loves them forever and unconditionally...?
Unfortunately this doesn't happen for many guys. The guy falls in love, he keeps thinking about her and imagining doing stuff with her... Then he meets her again and he is overwhelmed with his own feelings... she is now untouchable and pure princess-virgin, at least in his eyes... He is not able to push things forward with her, he can't have sex because his feelings are way high, and she starts hesitate about him as a viable mate...
He then gets even more in love while already in pain, and the more he keeps coming back and "fixing thing" and believing that she will change her mind, the more he is hurt... She then starts avoiding him, his ego kicks in, and he starts chasing her.... She'll eventually dump his ass, starts calling him creepy... he gets hurt and depressed even more, he will have hard time to go out and meet another girls because the thoughts about her is all his life....
If unlucky, he will then start voting democrats for the rest of his lonely life... Very sad. If lucky, he will find sites like GC and figure out what the problem is... Ask me how do I know... except I would never vote for dems, LOL
Anyway, IMO as long as you understand the mechanics of "being in love" you should be fine. Love is a fire, it's like playing with matches in dry woods. I also thought I had it under control, it was just a fun at first - then I suffered two of the most miserable years of my life... Beware brother, you may get hurt a lot even if you know what you are doing because you think you have things under control... There is always high potential of being dumped when you are investing too many emotions into a girl... she is simply perceiving you as less mature and more needy, while she is looking for The Man who can giver her a shag of her life, then walk away from her with no regrets or feelings...
So a great advice is to AVOID love unless you are at least sleeping with her. Sleep with a girl at least 7x before you even consider love, make it a rule... Always invest LESS into a girl than she is investing into you, emotionally, financially,... Make it another rule...
Another way is to let yourself fall in love, and suffer the potential pain from rejection. You may watch her going out with another guy(s) and having a great time, while she is totally cold towards you... while she is ignoring you as if you were nothing, and that really hurts... The good thing in this is, that you gain a great experience by being in love. You will understand many things here much better, not just by reading about it but by having own invaluable experience...
