How do I get over unrequited love with my best friend/roommate?

I've been in love with my best friend/coworker/roommate ever since he moved in with me six months ago. We'd worked together for about a year prior to that, but other than finding him really nice and cute, I didn't have much in the way of feelings until he moved in. We've grown so close and his personality is just addictive to me... he's attractive, he's kind, he's friendly, he's caring, he's funny, his voice and laugh comfort me, his eyes are gorgeous, he even smells good... I'm obviously smitten with him. But even though we flirt all the time and make sexual jokes with one another, at the end of the day, I can tell he doesn't feel the same way about me. He loves me to death (his words), but he's a very loving person in his friendships. I know he does not mean it romantically.
The issue is that I tried to move on from these feelings by distracting myself with dating apps. I've found a guy who is very into me and I do like him as a person, but I can't force myself to feel a romantic connection to this guy. I'm so hung up on my friend that it's killing me inside and I don't know what to do. (Moving out is not a viable option for either of us right now, which is the biggest suggestion I've gotten so far.) What can I do to move on from my friend and give this new guy a chance? My friend is excited that this guy is into me, but he is confused every time I say I'm "not feeling it" with the new guy. I'm afraid he's suspicious of my feelings and I genuinely don't want to ruin our great friendship. What should I do?
