OP's proposition to be discussed is "solipsism can't be disproven". Both of you then start talking about the psychology of the person who chooses to cram either solipsism or some other belief into their head and just "believe" without proof. This has nothing to do with whether or not solipsism can be disproven or proven. It's ad hominem (psychologization), listen to this at the timestamp:

Then begin studying logic. I posted a few examples of materials here:

One of the first things you learn when you study logic, which is a very important thing to know, is the difference between a proposition and an argument, you both demonstrate not knowing the difference. Picrel is from https://archive.org/details/logicorrightuseo00watt but all logic books talk about this difference early on because it's absolutely fundamental. We learn zero logic in school these days, you have to study it on your own, which most people don't do.
