Some say relationships take effort while others say good relationships shouldn't take effort to be successful. In the end what exactly is a successful relationship ? Who defines what a good relationship is ? It really depends doesn't it. There is no universal Bible about love or friendship.
To some it may be staying happy forever, while for some it can be about having lots of kids and taking care of them , make a great world for them or if the relationship is more of a friendship then it can be about having fun together, you caring for them and they returning back that care to you.
This is what I want to speak about, an individual's 'Personal interests'. You see in a relationship whether you are friends, boy/girl friend or husband and wife you really should not try and force the other person to like what you like. It just doesn't work that way. You just cant expect the other person to like what you do or to see and enjoy or live the way you like to. You see it all depends.
Each person has their own view to life and their own interests to what they enjoy in life. Whether it is going to the gym or playing with their dog or lying on the couch napping you really should not complain about it or feel dissatisfied about it. Just because they are with you does not mean their interests are suddenly going to disappear. Accept it as a part of life. You like or love the person in your relationship because you like certain qualities or factors about that person , never forget that ever while in a relationship and never allow an anger within you to form just because things aren't always working out your way.
My point is if you feel like your partner should see or enjoy things that you love to do , share it to them when they are free minded or relaxed and see how they respond to it. If they feel happy then go ahead and get deeper into it, do those activities together, it's a win for you. Or if it doesn't work out , don't try to force it upon him/her. Accept that he/she is unique and not like you and give them the freedom to enjoy what they like.
Accept that there is no such thing as "Your loved one will like everything you like if they love you".
Try new things everyday, see what works and you will eventually find things that you'll love to do together. But make sure to always give them the space and not trap their time devoting it all to you. Life is too short to do that.
Peace.
