Is love built?

Is love built or just exists? After four years together, I feel like my boyfriend is family...I care about him. I want to see him do well in life. Take care of him. But I don't know if I still romantically love him. Sure, it's been a while since we've spent quality time together or since he's done anything romantic or just a simple gesture like cook me a meal. I'm not writing off the relationship. He has all the qualities I want in a partner. Except he's a workaholic. I'm struggling be part of me feels like I don't love him anymore, the way I should and part of me realizes nothing is ever perfect so maybe I should just count myself lucky and maybe this is just how it goes for everyone after a few years together. Are you still crazy in love with your partner? Do they still 'get' you? Do they still turn you on, give you butterflies, do nice things for you without you asking??
