The way to keep you and your girlfriend together is to tell her that you love her every day. Another thing you should do is care for her, love her for who she is, make her happy, make her feel noticed, and make her feel like your Queen. If you want to make her even more happier then you can make poems for her just like I did for my girlfriend. Tell her this: I love you so much, till the end. I'll be there for you every day. And you are the most beautiful, perfect, amazing girl ever. <3.
