Thank you. Jeremy, this is a solution technically, but not a solution that I wanted. It prints 3 posts in 1 row, which is smaller than what I want.

A workaround that I will use is to completely hide each 3rd post on mobile screens. I ll use this css for anyone who wants to use it..

@media only screen and (max-width: 640px) {
	.entry div#jp-relatedposts div.jp-relatedposts-items .jp-relatedposts-post {
		width: 50%;
	}
	.entry div#jp-relatedposts div.jp-relatedposts-items .jp-relatedposts-post:nth-child(3n) {
		display: none;
	}
}

Works for me. Thanks for helping out, I hope there is a better solution in the future for this.
