Together-Breakup!!!

You have invested a lot of time and energy with him/her and after yaw have agreed to move in together, yaw get married. But after a while with life's experiences together things start to go sour to the point that you both agree that you'd rather just divorce/separate. Here in lies the problems:

You got kid/s
You bout a house that requires 2 incomes
The sex is good enough to stay
It's complicated to where you Hate to Love them, but you also Love to Hate them.
Everything is questioned in regards to opinions
You both agree to not let the child/ren see you argue
You sleep together to keep the 'Family' concept in perception of the child/ren
Bills are too much for just one person
You don't talk about it to other people/family cuz you know their opinions mean a lot to you.

Simply put its complicated!!!

We've all seen/heard where people been married for 18+ years and then get a divorce.

What makes a person sacrifice so much time and themselves to deny what could be a better life with someone?

Are the kids mindset, friends/family opinions that strong that we let that dictate our lives?
