Yes......He's my good friend, I will say dear X (simple his name) As we have been a good "online friends" more then a year & I just give support & encourage him once he on his duty on army. As a good friends we supporting each other & as we not really seeing each other in person & that's why I choose that words. I guess your correction is better so you could translate it into Turkish. Thank you :)

Btiara... I wish the english text was precise. I supposed that you are addressing your lover, so I translated the opening remarks as "sevgilim" (you could prefer aşkım, canım cicim etc...) If you are addressing your friend, then you should say "dear friend/name". Otherwise you leave the title ambiguous.

@ Nemit & Istanbul : çok teşşekkürler çeviri için (CMIIW) / Thank you so much for the translation. @ Anarcotaurus : I don't like & trust using web translation specially for sentence coz it's not translate the correct ones. As you can see even here there are 2 difference opinion. Anyway, thanks for the correction, if you dont mind you can write in Turkish the correction that you made. Thank you :)

Sevgili arkadaşım, umarım güvenli bir şekilde dönersin. Seni bekliyor olacağım. Senin için dua edeceğim ki güvenli şekilde dönebilesin. Sonsuza dek senin düşüncenle.

You have the translation in Turkish, so I'll choose to correct your english: "Dear, I hope you will return home safely. I'll be waiting for you. I'll pray for you to get you back safely. With your thought forever."
