How do you say in Arabic to We'll be together forever & to Happy Birthday ? - happy birthday in arabic to a girl

I take these lines in Arabic written on a picture with me and my friend and his birthday.

Please note that I am a girl against a boy. I need written in Arabic and the transliteration into Latin characters.
Can anyone help?

PS If you give a book to write the beloved, what message you? (Please write in Arabic, English and means both transcription).

Thank you!
