Its been a while since ive actually installed gentoo so i feel like a noob again. I just got done installing it and it keeps mounting / as read-only. When editing grub on boot I am able to change ro to rw on the kernel line and it will mount rw. (I am using grub2 btw). From what I understand there is a service or something that is supposed to remount / to rw. Im no sure if i need to edit a grub file or something else. Could someone help me? Thanks

Mounting root filesystem as read only may occur for some reasons. It may be incorrect file system structure, harddrive/cable/chip problem, high I/O load and other hard drive related problems, that forces fs to mount as read only in order to prevent possible data damage.
Have you checked your file system?
