I have occupied a room in freehold from a family for about 2 years now. There was never a lease.

For the past 10 months I have not been living there (but at my girlfriend's place), I go there once a month etc. I have not paid the rent for about 3-4 months now.

The landlord is saying pay the rent or else they can take "action". Should I be worried if I decided not to pay the rent? Rent is $800.

I never told landlord about staying at GF's place. We have been "texting"/"calling".
