Short love letter to my boyfriend

Hello everybody,

my boyfriend is Mexican and I‘m German. (Sorry my English is also not so good.☺️)
Our anniversary is soon and I wanna show him how much I love him into his mother language.

Could anybody translate me the following text into Spanish please:

Thank you for everything my love. I‘m so happy that I met you. I can’t wait to finally see you again because I miss you so much. I love you above all/over everything my life (mi vida/ vida mìo?). You are everything to me.

Those who didn’t believe in us will see that our love grows stronger and stronger everyday.
(Because he’s stationed in the Army here in Germany a lot of people thought that he’s not serious or we won’t make it because of language problems... (maybe someone knows a better text for this situation or maybe there’s a Spanish saying for a situation like that?)

Thank you in advance.

Muchas Gracias ❤️
