There is nothing I can do to change the way you feel.

 Im just sad that you can not love me the same way that I love you.

Because if you could, Happiness would be yours.

I can not make you love me 

I can not push you to be mine.

Only you know who your heart desires, but you shall know that I will never forget you.

I will always love you and any time in your life if you need anything just call me. 

Hissettiklerini değiştirebilmemin bir yolu yok.>>

Sadece, beni benim seni sevdiğim gibi sevemeyeceğin için
üzgünüm.>>

Çünkü bunu yapabilsen mutlu olurdun.>>

Senin beni sevmeni sağlayamam>>

Benimle birlikte olmaya da zorlayamam>>

Tek bildiğin kalbinin arzuladığı kişi ama seni asla
unutmayacağımı da bilmelisin>>

Seni hep seveceğim ve 
hayatın boyunca ne zaman olursa olsun herhangi bir şeye ihtiyacın olursa
beni araman yeter.>>

Bir insan aşık olursa, kıskanır, bağırır, kısıtlar, hesap sorar, sahiplenir; ama anlayana işte

If a person is in love, they will be jealous, they will shout, they will restrict you, they will call you to account, they will claim you, but look for one who understands (you)

Is this from Facebook? 

PS The ´will´ part can also be removed from the translation, ie they are jealous, they shout, etc

No, my boyfriend

....ama anlayana işte. How can we translate this? Like this "if you understood, you would appreciate it" It is not a literal translation but it makes sense. He will be jealous, he will shout, he will restrict you, he will call you to account and you will appreciate him because you know he does all of these because he loves you. And you will not say a word. That is just sick.

ahhh, thanks Gokuyum, I guessed the translation of that part wasn´t meant to be literal.

I agree these traits are a worry, not something that I would take as a positive sign, just something that can lead to problems in the future, especially if it happens now. These are signs of a dominating male in my opinion. 

Exactly. That is a macho behavior.

I seriously warn every girl about these signs.

Exactly, the boy friend should be told that LOVE is a two sided affair....if each lover shouts at, is madly jealous of, constantly criticizes and judges the other - that is not love; it is some kind of sickness.

He will not understand it, but it is worth a try.
