Maybe you are answering this because you are not very intelligent.

Yes, maybe my advice is not phrased with nice words, and? Calling it "immature" and "presumptious" (sic) it just calling names, it doesn't adds anything cognitive evaluable.

You seem to be very confused about emotions and other basic activities of the brain. You don't need to "think" to have an emotion (but maybe you need to think to understand your emotions, or figure them out). When you learn multiplication tables you learn an algorithm to do computations over a set of numbers. You need a finite set of instructions to achieve some result, that surely can be difficult. When you teach to multiply to a 9 year old child, you teach them an algorithm. But you don't teach them an algorithm to have an emotion, it's patently obvious: you don't teach anybody how to have an emotion.

You are doing nothing when you have an emotion: that's something that happens to you, not something that you do (but surely you can do things that trigger an emotion, but confusing an action that causes an emotion with the emotion itself is disingenuous).

Unless you're mentally challenged, only call things that you do (that is, that you have to follow a set of explicit rules or tactically learned procedures) difficult or easy, because you can do them right or you can do them wrong. You don't have to make an effort to have an emotion, because you are doing nothing when you have an emotion.

It's the chemistry of your brain, the product of millions of years of blind variation and natural selection responsible for your emotions, and that's it. Surely, we can think, we have language and we ponder about our emotions, try to find explanations for them and even try to control them. That is something that we do, but it doesn't make the emotions itself "difficult" or "harder" or whatever you want to call them.

The most hilarious part of this is all your intervention in this topic was to rephrasing what other users already say in a vocabulary that sounds "nice", adding vagueness that sums nothing to what was already said.

I don't care about being "nice" or say "kind words" about people and their sentimental problems on Reddit. You seem to think that calling trivial, simple issues "complexities resulting from the difficult emotions we have" is nice and kind. Nah, that manipulating people to make them believe they're problems are special and whatever. The girl that posted here was clearly headed in a particular direction: to manipulate her crush to leave his new love interest. That's not something complex or difficult, is very common and boring. Because is boring it should shut down as soon as possible, without niceness but brutal honesty.

By the way, for someone so preocupied about the complexities of relationships and emotions and blablab you seem very prone to insults and name calling. Maybe you are a little out of touch, and reading too literally in the form that I said some things?

Good luck, hope to write you back again when you're more relaxed and not so preoccupied with the complexities of relationship advice on the Internet ;-)
