You would have to convince the Dutch officials that this time, you won't overstay. Can you make a credible explanation why that won't happen? Saying "I wouldn't do that, honestly" won't be enough with your history.
It might help if you had a stable and well-paid job that requires you to return. Something no sane person would give up, even for a girlfriend. Earning more than you could in the EU ...
It might help if you were very young in 2013 and more mature now, but you are not much older now.
If you have lived together with your girlfriend for a long time, you might have a chance for a dependent visa. Ask on Expatriates Stack Exchange. (But personally I doubt that will work.)
