My suggestion to get out of the rut...turn the tv off....and talk....play a game you two enjoy (doesn't matter what), put some music on but do something interactive...go for a walk, watch a sunset together...something other than watching tv, or increasing your distance from her.
IMO right now, you're both letting the tv create distance for you in the evenings. Sure, you're sitting physically close to each other...but there's no interaction, no real interest in each other. I'm going to apologize for how this sounds, but it's the only way I can think of to put it...right now...you're just two bodies sitting next to each other, there's no interaction it sounds like. Am I interpereting this correctly?
Something I occasionally do with my H that ends up in some pretty good conversation is to just out of the blue...when things are quiet...ask him to tell me something I don't know about him, something he thinks I'd never guess...or that would surprise me to know about him....then I do the same. Might take a little to get a conversation like that going for the two of you...but I guarantee you there are things each of you doesn't know about the other, things that would surprise you. Even if it's something you did when you were a kid....that you've never told her.
