Manipulative?

My boyfriend, if I could call him that, has been lying to me for the past 6 months of our relationship about his job. He has lied to me and my family. He always said at the start of the relationship that if he ever caught me in a lie that I was done for and that he would ruin my life. I was petrified. He would constantly look through my phone and question me on my past relationships and sexual experiences, calling me a slag and making me feel worthless, telling me im not trustworthy and that i'll probably cheat on him even though i never would. Although he never laid a finger on me, i felt scared to even tell anyone else what he would call me or say to me. I think i want to end it but in my own head i'm scared and I need advice from the wonderful women of glow. I am now 9wks 5days pregnant with his baby and he still accuses me of cheating although ive not looked at anyone since getting together with him.
