Does it actually get better?

Lo 5 months Friday and there's no feeding routine. We settled into an every 2.5 hr feed for a few weeks, but now she's just not having it. She barely wants to go on the breast, I try to offer it her every hour, goes on one side for like 3 mins then turns away. That providing she even goes on. But when she doesn't go on she cries like she's not fed for days. Breast offered, fusses and turns away. Pulls a face at pumped milk and bottle. Then cries that she's hungry and this is the dance every single feed. Unless she's asleep or about to nod off I have no chance... And therefore she feeds regularly throughout the night. So tired... So defeated! Can't leave the house because she won't feed outside only in the darkened bedroom laying down. I do try to get back to feeding normally, no luck...

Does this phase actually pass or is this how things are now?
