I know nothing about your situation, but I know from my own experience that as soon as you have multiple developers working on a project, plus staggered QA/Staging and Production deploys, things get really complicated really fast. Then you add in stuff like experimental features (refactors, porting to new framework versions, etc.) that need to be developed alongside regular work without clobbering it, or features that get shelved while they are half-done, and things get just downright messy fast in something like SVN. So my guess is that you aren't stupid at all, but that you just haven't had to deal with that sort of garbage. (It's also possible your teammates simple deal with all this other crap for you, and don't bother you with the details.)
