It could be that you're just incompatible with the size of the acoustic body and fretboard of the guitar you bought. Some classical/acoustics are larger than others (Dreadnought.) The ultra-wide fretboards on some these guitar types can make chords seems really hard (harder) for beginners to learn.
I agree that maybe you should switch to an electric. The fretboard spaces are thinner than acoustic and chord-beginner friendly. The techniques are all the same on the basics and you mentioned you enjoy listening to rock, anyway. A natural progression, wahoo!
You can always return to an Acoustic when you gain a little more expertise. No harm in identifying weaknesses so you can build on them to become a better player!
And don't forget the importance of metronome/backing track practice.
