It sounds like the two of you want different things. Maybe he said that he's like you before to make it easier for you to move in with him?
Bear in mind though, it's not unusual for romance to die down through the cycles of the relationship. However, the speed with which this occurred here suggests to me the two of you desire different things on the personal level.
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
