jerking Off ...

I seriously don't know how to feel anymore.. I'm 6 months pregnant, 3 years anniversary coming up ( not engaged or married yet ) and I have brought the subject up multiple times. 
I feel that I can't deal with him watching porn anymore, I don't feel like my priceless lady cave is worth giving up on what I believe in. 
If you can satisfy yourself what's the point to wait for the good stuff and make it extra good ! I'm getting so sad I don't even wanna have sex anymore until he fully stops and show craving for it and appreciation.. 
I feel not taken in consideration, and frustrated because he is so set on his idea and so stubborn ... 
Any married woman thoughts to help me ?!
