Wendylon, so glad I can help a good friend like you.
Something needs to be taken out of your heart: fear. It's OK to do the stuff you do together on your own. This doesn't mean you'll stop doing it w him when he's home. What is happening is that you're associating the show or whatever other routine you have with safety. It's like me associating my old house with the M. But if you let go of fear and just be in the moment, you will feel more at peace and I think he will do so too.
Don't beat yourself up for being too clingy. Just take note of the behavior you don't like and don't repeat it.
I recommend watching the Eckhart Tolle/Oprah show on A New Earth, available on YouTube. I watched all 10 episodes and they were so enlightening! This was recorded a few years ago, but I guess I didn't know about it until now.
