Firstly . Your right in your saying under your name, this will pass, it's just a bugger not knowing when.
My DS went through something very similar and in my case it meant moving him from our room to his own in his cot (not saying you should do this). I also had to teach him how to self settle again as he was used to being rocked to sleep in my arms and he was just getting to heavy for me to rock for very long. I ended up giving him a feed and cuddle before bed. I would them put him down and let 'protest cry' for about 10 min. I would then go in and pat him to sleep without making eye contact or talking to him. I would stay with him till he fell asleep though (once took 45 min of patting). Just want to point out that his protest cry was more of the occasional yell or whinge. If he had tears or a 'real' cry I would get him up for about 15 min and try again.
Im not sure what will work for you but it can't hurt to try some new techniques. I hope you find an answer soon and can get some much needed sleep.
Oh it may help regarding EBM, my neighbors DD never took a bottle but after a week of trying she started taking a small sippy cup. It made it easier for her DH to do the odd night feed. Maybe it could help you.
