If you truly want a relationship to last a lifetime,both people need to understand one thing ...
You and your partner are different individuals, with two different lives, different upbringing, different experience, and different mindsets.
Therefore,it isn't necessary for of you think the same way about
Everything or react the same way in every situation,and that isn't a problem at all.
The real real question is when there is a disagreement, do you stand against each other,or do you stand together??
Wining every argument isn't what matters,
Understanding each other matters much more.
Even when angry, listen to one another,
Don't focus on whose fault it was,Focus on fixing each other's mistakes and moving forward together.
