Is this translation correct? (Japanese)?

Question:

I was just wondering, do I have this Japanese translation correct? I'm trying to learn Japanese and I constructed this sentence by myself, I need to know how I have it all correct...

えいえん に あいしてる よ。。。やくそく する。。。
Eien ni aishiteru yo... Yakusoku suru...
I love you forever... I promise...

Please and thank you!

Answer:

Yes, perfect!
You could also write this sentence with Kanji as follows:
永遠に愛してるよ。約束する。
