Jon, I suspect you could be right about being there to just pay the mortgage. She doesn't want your physical touch, she watches soaps every night and so has no time with you......are you sure it's a wonderful relationship?
You need to talk with her. She needs to know how you're feeling. Use "I" statements when you talk with her: "when you're watching soaps each night, I feel isolated and disconnected from you" and "I really miss the cuddles we used to have". The changes she makes (or doesn't make!) will tell you whether or not you're there to just pay the mortgage.
While I disagree with pcmaster's advice of controlling what she watches on TV, I firmly agree that you should not apologise for seeking physical affection. We should only apologise if we do something wrong - and seeking physical affection is not doing anything wrong at all. Instead of an apology, it's the perfect time to insert the *I* statement above. And she feels guilty, then GOOD. Perhaps she'll do something about it.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
