Single life brings back biological impulse

After being reintroduced into single life for a couple of months and surrounding myself with single female friends, I noticed a great change of focus in my daily life. When you start spend way too much time talking about boys with your girlfriends and buying something new every week (my excuse being retail therapy until I can tame my emotions again), you start to think, why are you all of the sudden doing all these things that you didn't do before you were single? The answer is... *dun dun dunnnnnn*

Finding your optimal mate!! Not really surprising, right?
Biologically speaking, we as a human race and as individuals, our goal is to reproduce (pass on our alleles to our offsprings to improve our own individual fitness). Recalling back to one of my older post about sexual selection, females have larger investments than males in sexual reproduction and therefore are more "choosy" (A. Carter, BIOL 312, CSULB). Females are constantly looking for their ideal mate, and since this is an important search mission, most females will only invest time in potential mating partners and not just any individual.

So what does this translate to? Most girls will only invest time in guys that they consider to be their potential "serious boyfriend material". And guys are more likely to invest time in girls that they don't see as potential wives. This can be supported once again by the biology of the male species.
As mentioned before, sexual reproduction investment is much smaller for males. Males can expense all of their energy in sperm production (whereas females have to expense their energy on egg production AND carrying the offspring), so their focus is to spread their genes and have as many matings as possible (once again, to improve their own fitness).

After being released into single life again, I am noticing how much energy and time I expense at finding the optimal mate, it is way too exhausting!
