Want to live alone

My roomate is dragging his feet moving out. He should've been gone a month ago but keeps coming up with excuses. My boyfriend told him he has to be out this weekend no matter what happens. I'm just losing hope something will happen again and he will be around longer. Last weekend was a medical emergency. I just want to live alone (just my boyfriend and I) already, I have never lived alone and I need my own peace and I feel im walking on a thin line trying to get there. I'm agitated, very thin patience, I dont have energy to do much of all lately but pushed myself to go to the gym today even though I just wanted to lay in bed and avoid everything. I've always had roommates but after this one no more. I feel im overreacting and just want it to stop already.
