Hello there…

I am much younger than you but I have been in a similar relationship..i dated someone who seemed so perfect at first,perfect to everyone and he was quick to proclaim his love for me but once I got to know him..he was a different person…later on I realized that he was a narcissist…(have you read about it???)..maybe you should try and research more on narcissistic behavior to see if it fits your situation…and about you leaving him,I think the sooner you leave the better for you..he sounds very manipulative and abusing…and such people rarely get help…leaving him will not be easy but the more you stay with him,the more this will go on if he doesn’t get help and your time will be wasted…

be strong!!..and most importantly look out for you when you still can.
