At What Point Do You Get Mad

Meagan • Miscarried 2, thinking about trying again. Wonderful doggy mama of 2 morons.
So, my partner and I have been together for a while now, a few years, and he has just given up on making me orgasm. He used to try. He used to put effort in. He used to make me cum.
 
But, now, it's like I'm just there for his use. Every once in a while, he'll take his time and go down on me, but it's never for very long. And it kinda hurts my feelings that he thinks it's okay to enter me before I'm even a little wet. I'm pretty upset that he stopped caring if I enjoy our sex life or not. 
 
Phase or time to pull the plug? Is it a rut couples go through or are his real colors finally coming out?
