Still breastfeeding?

Is anyone else still breastfeeding another child? I have a 16 month old who still nurses and ever since I found out I was pregnant she is constantly asking to nurse. My hubby acts like I am torturing her, and I swear I do not want to upset her but I just physically can't nurse her every single time she wants to anymore. I just got kicked out of our room so he could attempt to put her asleep because with me in the room she just cries and cries signing milk the whole time. How do I get through this?? Will it get any better?? It's making me question whether I want to nurse through this pregnancy at all and definitely making me feel negatively about tandem nursing. I really thought it wouldn't be this hard.
