Be done! You deserve better. Emotional abuse (even if it starts overnight or there may have been a bit along the way) does not stop overnight, generally it will gradually increase. Also, be very concerned about the lying - it seems to indicate there is probably more behind it than not.
I was in a similar type relationship and I was the only one that did not see the "abuse" and cronic lying that was happening. Now that I am out of it I can see the escalation from early on.
