Just need to get this off my chest

I am starting to fall out of love with my boyfriend. There was a time when I thought he was the one and now all day long I picture a life without him where I travel and meet new people instead of stay doing the same old thing. He hasn’t really done anything wrong just perhaps we both got too comfortable. I live in a constant day dream of a different life so that I can make it through the days. I find myself staring off thinking of a different life. Part of me imagines life with this one guy who I met and it was just right person wrong time, I wonder what he’s doing or if he ever thinks of me. It would be nice to feel like someone is interested in me again. It’s really hard to leave when they have done nothing wrong, I’m not sure what else to do. Constantly thinking of a new life makes me grow further from him and reality but it also keeps me sane and happy. No idea where I can go from here it’s eating away at me. Rant over
