Ok so a bunch of people kept having this problem so I figured I'd make this to help out.
Portals in the main world will all link to the same portal in the nether if they are within 1024 blocks of each other. To fix this follow theses amazingly easy steps.
Step 1: Build a portal in the main world and write down its coords.
Step 1.5: Divide those coords by 8
Step 2: Travel into the nether (if your portal goes to a blocked one use someone elses)
Step 3: Travel to those coords you got after dividing
Step 4: Build a portal and light it up
Step 5: Profit (oh and if you did it right both your portals should link)
