Time, also known as putting them as a priority.
You better take care of it before its too late.
Here are 10 of the most important things you should not withhold from your partner.

Understanding
You must both set ground rules and have an understanding that this must be followed and done accordingly.
And for the other, you have to understand each other without keeping records of wrongs.
You have to understand each others differences and that you are allowed to like different things.

Communication
Each couple should communicate, even at the bare minimum.
Communication helps people to reach out physically, mentally, and emotionally to one another.
You have to let each other know that you are on the same page.
Communication also helps to lessen fights and arguments.
Theres nothing wrong with keeping in touch with each other.
Time
Also known as putting them as a priority.
Freedom
I know you love him, but give him some space to breathe.
Guys dont like to be controlled or to be limited from the things that they want to do.
Privacy
Common mistake of everyone.
But if they do that, they no longer have their privacy.
Like I said, you cannot lock someone up to check that that they really love you.
After all, they chose you.
Being open in a relationship means a lot and it makes it easier to be able to trust them.
Love is about being secure with someone.
Imagine if you hate how he chews so loud and you will not be honestly to tell him that.
Do you think he would change his bad habits on his own?
Support
If you really love someone, you will support them in whatever it is that makes them happy.
Be there when he needs someone to cheer him up and not put him down even more.
It will be heavy, but worth it.
You gave him your heart, let him prove to you that he deserves it, and vice versa.
Trust is very hard to earn, especially when it has been lost.
You cannot fix a broken and shattered plate, so be careful and dont play with it.
Intimacy/Fun
Of course, fun adds the spice to every relationship.
If you take that away, then I dont know what else is left.
So travel as much as you need.
Walk in the rain and dance in the dark.
Do whatever it is that makes both of you happy.
Also, intimacy is a major component of every relationship.
Affection
If you cannot show love and care to your partner, then why are you staying?
Why would you hold them back from looking for it somewhere else?
If you love him, show it.
That is the point why you chose each other.
You cannot deny someone what you have promised from the start.
You cannot deny them the love they deserve or else let them go.
