I know your pain, man. Thankfully it slowly faded away for me in a period of about 4 months. I love my SO very much, and I know she loves me, but it was extremely taxing on our relationship. She didn't understand it very well at first, and for a while thought I was just up talking to some other girl, because when I couldn't sleep I would just try to zone out and watch movies, play games, read, or even just stare into nothing, so from her end, all she saw was me disappearing for 7+ hours a night while she slept. I remember breaking down in tears and trying to explain to her what it was like, trying to fight it and lay down, taking pills, seeing doctors. Thankfully she learned fairly quick and was extra sensitive about it from then on, but nothing was worse for me than being accused of cheating, when in reality I was just in another room struggling to tire myself out enough to sleep. The worst part is she's one of few that comes somewhat close to understanding what it's like. My friends and family have a hard time trying to grasp the concept of it, and are often saying things like "well just go for a run, or do some exercise, or go to bed earlier." Then there's the people who think they have insomnia because they choose to stay up all night because they're young and dumb, and want to play Halo until like 2 am, so they try to relate to you and just come off as offensive since they truly don't understand. It was such an emotionally taxing time for me. I never want to go back to it again, and I enjoy my sleep. 9:30 in bed every night, awake at 5:30 every morning. I had an extremely positive shift in my life that helped reduce a lot of stress and anxiety that helped curb it.
