My personal tip for you is to surprise her with a gift. You don’t have to wait for her birthday or Christmas just to give her something. Giving a gift is not buying her love, but showing her how special she is to you. Your gifts don’t even need to be expensive for her to appreciate it. Picking some souvenir items for her when you are on trip is a nice way to tell her that you are always thinking about her.
And of course, don’t forget the special occasions. That’s when you really need to show her how much you love her. Again, it’s not about how much you spend for your gift but the effort you put in getting her something that she will really appreciate. Having said that, now’s the right time to think of something out of this world to give her this coming holiday season.
