Why do we get into a relationship with someone we barely know?

Relationships are exciting! It's fun to just dive into the life of another person, learning about their unique passions, history, and beliefs. Meeting people can be very stimulating, especially when there's a romantic aspect in mind. While there's a lot to be said about pursuing relationships with people we already have a good handle on, there's an extra layer of excitement with wearing your heart on your sleeve and flying by the seat of your pants.

The excitement! You don't want to be with someone you know almost as well as you know yourself! There's no excitement in that.. No risK!

I believe sometimes the unknown is exciting for us because it is unknown, so we decide to dive in head 1st because of the newness and excitement of it.

We all get to this philosophical question at some point (I usually think about this when I just got into an argument with my significant other and wonder why I put myself through this). I guess its like an intensive version of a friendship. You meet, think the other one is quite a cool person and spend more time together. For friends, that's it. You see each other regularly, ask for advice, ideas, do things together. For love interests at some point you take it a step further. I don't think you'd get into a relationship if you didn't feel deeply drawn to him/her, and by that point you know the basics about them, their views on certain topics etc. Later on, when you fight and make up, you see whether those views on life fit yours or not. I believe that you rarely ever know someone as well as you think. 80% of their thoughts are happening without you knowing, and no matter how much you talk about things, there will be new stuff to discover daily. Sometimes those things make you leave (like my ex, being against condoms and months later telling me he considered abortions "murder", no matter what others say), sometimes those things get you closer together (finding out that you both want to volunteer in an elephant sanctuary but feel "guilty" not offering your services to an orphanage first, for example). Its just how life works. For me, relationships (love based and friendship based) always work like that, and it's what makes them interesting :)

We get into relationships with people we barely know because of exactly that reason. Since we know nothing about them, we create an idea about them based on what we are looking for. Therefore, they seem so perfect in the beginning. We aren't dating them for who they are but who we make them seem out to be in our head.

First of all, we should not get in to a relationship with a person we don't know. If it happens, it should be due to attraction !

It's exciting, especially with a change in scenery (something that you've never done or experienced before), and love is a curious thing to experience.

usually it is because of infatuation and/or the self consciousness of not being in a relationship and finally having the chance to be in one.

The answer Is dopamine. It's a decision based on initial attraction and since both persons are willing there isn't a barrier to contain one enough to process the rational outcome.

Human nature. We're quite trusting compared to other species. Until and unless something traumatic happened and you start having trust issues.
