Can I learn to play guitar without lessons?

I have only been having lessons for a year, and I have learnt to read notes and play basic chords, and do the 3 scales. But I am thinking of quitting guitar lessons and learning the rest by myself. Would that be wise? And also, would I be able to learn guitar tab and chord progressions on my own? Where do I go from here?

What are some easy songs to learn/play on acoustic guitar?

I’ve only been playing guitar for about 3 months now, and i know the basic chords for the most part.
Can you give some songs or good websites that have easy songs to learn/play on acoustic guitar?
I’m into 80’s rock, nowadays country, Jason Mraz, etc.

Thanks so much in advance! =D
