Perhaps you moved in together too soon? Two months isn't really enough to fully get to know each other. Relationships are like a fine wine, they need time to mature.
Whether you stay or leave now all depends on the circumstance, of which you will need to provide a bit more detail.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
