The meaning of a Relationship (am I delusional)

What even is a girlfriend? Whats the purpose? What even is a friend? Is a Girlfriend just the extension of a friend? Implying, that you have se x ual contact with that person. A friend as I see it, is a person you can talk about anything with and someone who has he same needs or interests you have. Think about the last time you talked with a friend! What was the topic? Mainly, and this thought reoccured many times, we are just talking about Problems or stating obvious facts, sometimes we answer questions, that help the other person, but at the core of it, talking to a friend is just like speaking with a humourous machine, replying to whatever you said. Due to these points, the human in my opinion is just a „helper“. God created the woman to help the man, which is what my thesis underlines. Not only is the woman another „helper“, no she is also a se x ual partner. But what is the point of having a girlfriend, when you are just spending loads of money on her, to have a friend, that you have se x with? You could have se x without having a girlfriend, additionally you would have variety. The only real reason to have a girlfriend, at an age, that is not typical for marriage, is having constant access to se x. Further down the road, when marriage is not a ridiculous thing to think or speak about, nothing changes!

The only reason why a human would need a partner, would be, if that person got someone pregnant or is pregnant themselves. The thoughts repeat themselves, forming a logical circular chain of events. Raising a child, is basically just being a „helper“ once again, but this time for your child instead of a random humanbeing. Due to the help the child receives from their parents, he/she acquires a toolset, thus being able to help others.

Dont get me wrong, I make out with girls frequently, I am not ugly, but somehow this is my perception. I have never been in a serious relationship before, that lasted longer than 2 months, one broken up by me, one by a girl. If anyone has an opinion on this thesis i stated, please comment.

I am sorry if there are any spelling mistakes btw, I am german so its not my mothers tongue.
