you need to go out more just the two of you together, do what you liked doing together when you first meet,
you both need time out with friends, alone and together,
part of the resentment sometimes caused when one person is off out, is that remainder person, really feels the lack of time out together, that time that is all positive and reminds you of the good bits of why you are building a long relationship,
when you have children, it's very easy to just to grab the time out individually, and then the only time you are spending with your partner, is in your stressful living environment, surrounded by reminders of things to done,
If we notice we are a little off kilter with each other or ourselves, we try to grab a night away together, get a friend in, leave.
I have a friend who's children are grown up now, she has known ours all their lives, she kept telling us, that it would do us the world of good, eventually we got around to it, and the change in overall outlook was massively improved, I recommend it.
just a bit of us time, chatting, late rooms is your friend, we go local, so not to waste time on road trips, we go somewhere you can have a nice walk, just spend time together, eat a picnic, night in somewhere lovely(late rooms, you really will find a good room for under £60) eat breakfast, walk, have lunch, go home, knacked children, really enjoyed the fun friend who misses having little ones, they go to bed , nice night in together, because you have just had time together and re connected,
we do an exchange with friend, she is single and we do her DIY work, we run a building firm, so she always loves it if she can convince us to go away as then she doesn't feel bad asking for the next job to be done,
Honestly if you can give your relationship these little MOT/services, you will find the comfort of team work feel will return , and instead of one person being perceived to be abandoning the other, the person left in will feel glad that the other is doing an activity, as they are assured they are the priority.
