What is the possible psychology behind the fact that my DP (no children involved, we are also rather young) can spend his time productively alone while I'm out of town, but not when I'm at home?
To be more specific, I have had issues with him not giving me enough space, wanting to spend a lot of time together, finally accepting that I have my own things to do and friends to meet and things to do at home so I cannot sit beside him or hang around with him all the time. However, he still just lays on the couch when we are both at home. He does household chores, ok, but other than the bare minimum he just lays on the couch and watches TV or Youtube. Whenever I suggest to do some projects at home together, he says yes but shows no further enthusiasm. Whenever I suggest for him to take on a hobby or do something alone, so I can have some privacy at home, he finds all kinds of excuses or says yes and then does not follow through or is sulking. He has no friends to spend time with (or rather makes no effort with the few he actually has had as friends); he won't visit his family alone (although they always invite him).
However, I have noticed that recently whenever I am out of town (I have had a couple of few-days-long work trips lately), he is very productive - does the home-project, goes out to jog or walk alone, does some things in computer that he has talked about for weeks or whatever. Just - finds ways to spend his time productively without just laying there and waiting for me to finish my stuff so I can be there next to him and be some kind of amusement tool (it feels to me like this, I do not know what he really thinks).
Is it something worth discussing with him? Could it improve if I point it out to him that he seems productive when I'm not there, but not when I am home. We have talked about these things one way or another previously, but mostly nothing has changed. I thought that he is basically incapable or uninterested of finding things he might be interested on doing alone, so I have tried to push away the break up thoughts that regularly lurk around in my head. However right now I just had the light-bulb moment that he actually IS capable and IS interested in doing stuff alone. But why not to do these things when I am at home to give me some privacy (alone time) at home when he very well knows that it is important to me?
