It depends...each persons skin is different. The person that told you that might have dryer skin and might not need the primer. Most people do need a primer if they are combo or oily (combo people tend to need it in the oily areas). If just moisturizer isn't working for you (which it never did for me either) then try a primer. There are no right or wrong "answers", steps, routines, or rules. It's all trial and error and figuring out what works for YOU.
Now I will say this, if you are applying you foundation with your fingers, then the oils from your fingers might be what is causing it to seperate. Try applying using a foundation brush or a flat top buffing brush. Elf makes some decent ones that are cheap ($1-$3) and you can find them in Target. You can also apply using a make up wedge/sponge/beauty blender and get good application (I use an elf foundation brush and follow up with an Elf flt top buffer to work everything into the skin). Also, you might want to set your foundation with a bit of powder. That will help it "stick" to your skin better also.
