Ok, so I finally managed to actually get something going, thanks and big shouts out to @Ferrybig for his input.
So if you create a Batch file, you would start out your script just as suggested above from @FerryBig
java -jar .minecraft/launcher.jar --server <ip here> -- port 25565
Nexe, editing some parts with your own server address and port number. You can also even adjust the amount of ram as well, to suit your needs. Below are two examples:
java -jar launcher.jar --server youripordomain.here --port 25567 -Xms1G -Xmx3G -d64 -jar minecraft_server.1.13.2.jar
Edit the port number as well, be sure to leave all whitespaces as they are.
The next big fact or you will face your client crashing while trying to connect, is make sure
jar minecraft_server.1.13.2.jar version matches
Save your file like START.bat and hold shift + right-click anywhere near the bat file you've just created and choose Open Powershell Here or whatever command interface you want to use.
This is what the final code should look like
java -jar launcher.jar --server mc.westeroscraft.com --port 25567 -Xms1G -Xmx3G -d64 -jar minecraft_server.1.13.2.jar nogui
Type in the files name you just created like: START.bat
Watch the magic happen. :) Thank you.
Also, this would help if you have a copy of your Launcher.jar file in the same directory as your .bat file
