The Point of Diminishing Returns

In everything in life, there comes a time in which the effort you once put into something is no longer satisfactory, and when your return begins to decrease as your effort begins to increase. You will eventually need to take more of a drug to realize its high. You will need more alcohol to get drunk (A rant for another time, but alcohol is a drug, and I dislike how it is separated categorically from things such as marijuana, cocaine, heroin, etc... by most people). This point is reached because without it, there would be some endeavor which could have limitless earning potential. The major thing I would like to focus on with this right now is with interpersonal relationships, specifically romantic ones. There comes a point in relationships in which the novelty begins to wear off, where people get too comfortable, and where it stops being worth it. For me, it seems most relationships hit this point at the three month mark. However, it varies girl to girl, usually inversely proportional with the amount of sexual partners she's had before me. I won't bother breaking down the specifics, or every reason why this happens. To be honest, most of these reasons are unknown to even myself. Irregardless, it doesn't matter either way because the why in this case is inconsequential. There are a number of signs which will show you that a girl has hit this point, most of which are minor and don't apply every time. However, the one consistency I have noticed regarding this subject is a single sign. Maybe it's due to a sample size, but the one thing every girl does when this point is hit is that she stops rationalizing my behavior. She stops defending it; not that I expect to be able to do whatever I want without being reprimanded, but a girl will start blaming me for things that she normally would not have. The sex will wear off too. In order to keep the relationship going past this point, it's going to require the sacrifice, in any magnitude, of your balls and your spine, as well as an increase in effort. You're going to have to start dealing with shit. It's going to stop being fun. If you truly believe you love a girl by this point, (Spoiler alert: You don't), you can stick it out and make your life hell past this point. But from experience, it's not worth it, and it never gets any better from that point forward. You have to realize when to cut your losses and move on. Not knowing is the Achilles' Heel of many gamblers, alcoholics, and addicts alike.
Commitment is something that is only searched for when you think, or even know, consciously or unconsciously, that you can't do better. True love doesn't exist, and monogamy is absolutely acceptable during the time of the relationship, as you shouldn't expect it unless you're willing to give it, but the idea that you should someone should be chained to you for the rest of their lives is rooted deeply in insecurity. Avoid it and any thinking that can relate to it.
