Even if we can't be together in the end, I'm glad that you were a part of my life.
No, seriously, I mean it. Do you know how happy I am when I'm with you? You are so sweet, nice, charming, gorgeous and extremely funny. I've never met such a charismatic person like you. I like it when we're holding hands or when you smile at me whimsically. I like your little surprises. I like it when you kiss me on the cheek or on the forehead. I like your voice, your accent and the way you talk. So I just enjoy the precious time with you and won't think about the future because I can't imagine how it'll be when you're not here anymore. How you could still love me after all the time we can't see each other. It would hurt and I'd be sad. So I will push these negative feelings away and appreciate every second I spend with you instead.
And if our paths separate, it'll be okay because I know that certain things will stay and I can let you go. I'll keep our precious experiences deep down in my heart and will be grateful for all the things you've given to me.
