Is there such a thing as a “Plug n Play Relationship” out there? One where two people have exactly what each other are made for without any modifications at all?  I say “NO”, and that is perfectly okay.  The problem is that people expect each other to be who they are today and remain that person for the rest of their lives. Or the other happens, and they are upset because they do not “changed” the way they expect them to. We change every single day and unless the two people change in the exact same way at the exact same pace they will never be the same to each other down the road. Then people get upset at each other for not being who they were and that is unreasonable.  None of us are the same people we were yesterday much less 10, 20, 50 years from now.  You either accept the person each of you have become or you accept that you are not compatible as you once were and you agree to part ways. There is no such thing as the “Plug n Play Relationship” that just continues to fit perfectly over and over.  Be okay with that and communicate with each other.  The worse thing you can do is hide the fact that your wants and desires have changed over time, or try to be something that someone else wants you to be and then find later you can’t be that.  Resentment then sets in and one or both parties feel they have been misled as to who you are.  Nothing is Plug n Play so just be yourself and be open with yourself and those around you as to your weaknesses and flaws.  Once you are able to acknowledge them you are able to work on them and being open with others will have the opportunity to work with you or decide if they like you only as you are or they want they same thing for you and will help you to grow.  Never expect that Plug n Play is what you want, because you have to know things today are not as they will be tomorrow.  Be ready to adapt and there may not be an adapter for everyone in your life when change happens.
