It's not that your son hates to sleep...it's that he enjoys time with you more! He would rather play with you, talk to you, get rocked by you, etc. than stay in a darkened room alone. When he realizes that he's alone in the room, he cries and knows that you will come to him. This is very common and appropriate for his age!
I recommend finding a sleep training method and sticking to it. There are many good books available. With both my kids, I have had excellent success with Dr. Marc Weissbluth's, "Healthy Sleep Habits, Happy Child." The book is organized by the child's age, so even if your husband is going out of town soon, you can immediately access the section on 10 month olds and go from there. You don't mention when bedtime is, but since fatigue causes increased arousal in children, perhaps his bedtime is too late and should be earlier. The sleep method book you chose will, most likely, give you guidance on this too.
As for the night feedings, you may want to check with your Pediatrician. Mine instructed me to end night feedings at 9 months -- she said that there was no need for food at this age and that my child was using them as a "social visit" from me. But you should probably check with yours.
Good luck! Healthy sleep is SO important for our little ones. I hope you can get some relief before your husband leaves town.
