"I love you. I do." He didn't think he'd ever stop loving her, not really. Just like he still loved Tana. "I just think I'm where you were before you started seeing Chekov. I just need some time." He needed time with some because he'd had plenty of time being alone. Or at least he needed time alone when he felt like he actually was alone and not waiting for something that might or might not happen down the line.
