I Want Someone I Can Tell Anything To

From the time you are united, then from then on, what effects you both does need to be said.

Old past events, that have no long lasting issues, don't need to be told.

Do know that both of your insecurities can come to the surface, as we do get triggered (You are not always upset for the reason that you think you are - old issues trigger) She to will get upset from childhood/family dysfunction ...so you will too .....

How your family and her family dealt with life ...

Money
sex
health
home
food
cleaning
cheating

All the above will factor in.

Then your fears in life.
Fear of ageing
Fear of death
Fear of been alone
Fear of failure

When her insecurities do surface, help her work through them, then you both can grow.

Be able to dance with changes - as the constant in life is change.

Quote for you:
The happiness of your life depends upon the quality of your thoughts. Therefore, guard accordingly; and take care that you entertain no notions unsuitable to virtue and reasonable nature.—Marcus Antonius.

There really is no such person that you can trust that much! Some things are never meant to be revealed !
