You have said that you have tried to spend extra time with them but "they all like to do their own things". It sounds like they only miss you because you have left them to do something on your own. They may feel left out, as if Aikido is somehow more important to you than spending time with them.
If like you say, they do there own thing when your around, it sounds more like the problem is with them, not with you or your Aikido training. I'm not fully sure of your situation, so I don't know if getting them involved with Aikido will work, or if you have tried to do this yet.
I think it is the age old situation of people not missing or appreciating something until it has gone. At least you know they care for you, otherwise they wouldn't be bothered by the fact that you are not around all the time.
It is important to find a balance in life, it can be tricky to find and may take some time. I hope you can find it.
Good luck and good training.
