My best thought is first of all....KUDOS to you for being pro-active!!!
Next....talk to your H and tell him how you are feeling and that you are sorry for the pain you've caused (albeit unintentionally I'm sure)....and ask for him to give you time to show you want to work on this.
Now...don't be surprised if he's cold to you at first. Speaking as someone who has been rejected time and again by her spouse....we won't easily trust that the efforts made are permanent. All too often when our spouse makes an effort it's short-lived, it doesn't last, it's not permanent. So, when someone, like yourself, decides to make a permanent change it will take some time for us to believe it's permanent....try not to become discouraged in your efforts ok?
You might even ask him...in a calm rational conversation, what it is that he remembers that you used to do, that for whatever reason (kids, work, schedules, life etc) you've stopped doing....that he misses. Many times it can be those little things that we stop doing that we miss the most.
As for being more sexual....be consistent. Be more physically affectionate, perhaps send him some suggestive text messages on his phone (I just tried this and seem to be getting some success)...try some different things you think he may like.
But...most of all, try not to become discouraged in your efforts. It took time for him to get where he is emotionally, it will take time to turn it around as well.
