<human>: Can you summarize the given text in a few sentences?

I am writing this at 3:34 am because I can't sleep.

My fiancé (Ben) is great. We have no problems in our relationship and I am super excited to marry him in 2 months. He's my best friend. He's also a bed hog. We have a queen sized bed and he takes up at least 80% of it. I have inflammatory arthritis so I need to be able to stretch out my arms and legs but I can't because he is right up against me on one side and the edge of the bed is on the other. He always pushes me toward the edge of the bed in his sleep and will even put his arm and leg on me. It's gotten to the point where I can no longer sleep in the same bed with him. However, we do not have another bed nor the means to purchase one. The couch is also extremely uncomfortable to sleep and also doesn't allow me to stretch out like I need to. I don't even need a ton of room, half the bed would be fine. I end up staying up all night and sleeping during the day since I can't fall asleep with his elbow in my face. What can I or we do to solve this problem so I can get some sleep?
<bot>: fiancé hogs the bed and I can't sleep. No other bed and couch is not an option. What can I do?
