There are so many ways you can love a person, may it be through giving her or him some gifts or maybe just by telling it and reminding him or her of how much you truly love each other. You can play it off cool but at the end of the day, the fact that you mattered to him or to her will show off.
The best you can do right now is to tell the person you are in love with that he or she matters in your life now and that you plan on keeping it that way for a very long time, maybe for the rest of your life.
In that case, I love you this much memes are necessary so here are some memes to show how much you love that person so you can use them wisely and just have fun telling it to her.
