“Show, don't tell” doesn't apply to this individual. If you don't tell your lover you love them, they won't feel loved.
This isn't insecurity; everyone feels love differently. "Words of affirmation" people need to hear your sentiments.
There is no such thing as an excessive number of praises.
A genuine card or letter with a few phrases about why you love them will be treasured and read hundreds of times. This present means more to a word person than anything rich.
If you're not a wordsmith, your spouse doesn't need fancy words. You're loved. They want your opinion, even if it's not well-spoken.
Praise your companion regularly in their interests. Tell writers what you like. Applaud their housecleaning efforts.
Express yourself on significant occasions. Add some text to store-bought cards.
Send them an unexpected message a couple times a week to let them know you love them or are thinking of them.
Uplift your companion. Listen without interfering. Remind them of their strengths to help them get through this.
Saying "I love you" too frequently never ended a relationship.
Be honest. Words of affirmation partners need loving words, but not phoney ones. Insincere remarks might be worse than none. Just be honest.
