dnd 5e – How to handle not being able to attend as often as I would like

I've been playing with a group for about a year. I have no complaints about my group, I am the problem. I am the only one who has children, and unfortunately for me, my wife is not exactly supportive either. As a result, the rest of the group plays every week, I am lucky to do it on average every 3rd week. It made me feel frustrated enough to want to give up, not because I do not love D & D, but I constantly lose the content I really want to participate in and I feel like I'm disappointing my group.

What I'm looking for is any strategy that people have found to work in a situation like mine. Specifically, how to manage a group in which only one person can not be there regularly but desperately wants it. Is there anything I can do to keep myself busy in weeks that I am not? Also, has anyone found a way to handle this relative to spell classes? I play with a bard, and if it is weeks before I play, I am usually recovering from a full rest, when the rest of the party is quite animated; As a result, I do not really care about managing resources every time I play, as it is almost guaranteed for the next time I play, it is likely that weeks have passed and I will leave a kind of "rest".

Appreciate everyone's thoughts!
