Honestly, he is more than likely trying to understand all these emotions and feelings that are coming upon him. Think about it like that. It can be a lot, but give him his space and maybe lay off any additional meditations that will make it even more overwhelming. I would stay away from BWD right now. I think if you do PW once or twice a week and just do gentle thoughts that would be great.
Don't think of it as him being distant, think about him figuring out the words and ways to come back to you. He wants to make sure he can grasp it all and be all that he can be
Also, don't worry about that meme. Imagine him posting a picture of you guys together.
