Im so done

So my daughter almost 20 months now right and were still nursing to sleep everytime even nap times. Not because I want to but because my husband doesn't like her crying. At 6 months I wanted to start transitioning her to her own bed but if she cried even just a little he would go and pick her up every single time. Then we had to have her tonsils removed because she had obstructive sleep apnea. But here we are still nursing still sleeping with me and I get very little sleep. Dont get me wrong i have loved the journey of nursing and co sleeping but my supply is very little and I'm super tired. I just want it all to stop but the moment he hears her cry he has to run to her. Now that shes gonna be 20 months it's just gonna be so much harder and I feel like its never gonna happen
