Yeah, I think everyone needs to go through this shit at least once - it teaches you a lot of lessons about life. Years back when I was much younger and very immature, I contemplated suicide, lost 10 kg weight, made an ass of myself, and all that. But that experience did me a world of good.
I have realized that it is pointless to think about all this filmi "true love", "saath jiyenge saath marenge stuff". With subsequent girls, I have my fun, treat her like a queen, and realize that it might end anytime - I constantly keep myself open to the possibility that it might end any moment. When I see indications that it might end soon, I start looking out, and end it myself before she can. I
never ever cry and beg and chase her - I did that like a mad fool the first time, for weeks and weeks. That just makes you an object of contempt and derision.
