It's "Containment"!!! There I said it. So what do I mean you say?
Life presents challenges every single day, and the more we develop as a species the greater the challenges. He/she comes home and is tired, either sat at an office surrounded by co-workers of all types and personalities, or his/her work is physical, might be all day on the streets fighting traffic or helping people, encountering tons of challenges and all he/she wants to do is go home and be with you. Maybe he/she wants to share his/her day maybe not. So he/she gets home and you've been dealing with your own day to day challenges, sometimes less sometimes more, but it's life and stuff happens all the time.
No matter what our lives are like or what we go through in a day, its just that, a day, and you can only deal with what you are equipped with and sometimes we are either not well equipped or have too much on our plate so we let out the 'Monster' that lives inside of us and we need someone who loves us unconditionally to help contain that 'Monster Within'. Not to judge it, criticize it, fix it, label it, but simply to help us contain it until we recover our balance and our harmony once again.
I don't believe there is any "Free Will", yes we choose who we marry but can we choose what he/she will do in any certain day? we can decide to have kids, but can we choose what they make of themselves? we can choose our careers, jobs and our friends, but that's about where the "Free Will" begins and ends because outside of our choices there are all these circumstances that are totally out of our control that can make our choices either succeed or fail, so for me what works is having someone to LOVE unconditionally who wants to be loved and LOVES me in return the same way, so much so, that is willing to help me contain my 'Monster Within'.
Make sure the partner you chose to share this life adventure with is helping you contain that monster instead of being the one who creates it, look inside and see if you're not the one creating theirs, be more selfless and help them become a better version of themselves, be brave, caring and do something about it. It is worth every effort you make.
Are you containing each other with LOVE!?
