I definitely understand that as we get older and grow we change. Our interests may change, our hobbies, what we find fun, etc. Part of growing together with someone also may mean every once in a while you may have to suck it up and go to a concert with your partner. You may surprise yourself and actually enjoy it. But if you are the type of person that needs a companion when you do things you also can’t expect your partner to do everything you enjoy so a good friend of the same sex would be good to have. For some of us ladies we get very emotional when our partner doesn’t want to do something especially something girly with us.
If you and your partner enjoyed going to the movies during your younger days, there is absolutely no reason that you can’t do this during date nights. If you liked cooking together then do this. Do not allow yourself to be consumed in the everyday tasks such as working, cleaning, cooking, etc. If there is an hour before bed and there are dishes in the sink, and the kids are asleep, leave the dishes, they can wait. Use this time for you and your partner to talk, spend time together.
