It seems that you are a Connecticut full year resident for 2019. moving forward if you use the New York apartment as an abode (place where you live), you would have to pay both New York and Connecticut if you keep your CT apartment and reside there more than 183. Just because you purchased the apartment in New York, if it is not your living quarters (visits to your family are fine) you do not establish New York domicile so you would not have to file New York state tax as resident.
