bana guvenmeni istiyorum. senden gercekten cok hoslaniyorum. sadece seninle birlikte oldum birbaskasi olmadi. suan hayatimda sadece ve sen varsin ve sen olacaksin.

I want you to trust me and I like you... this is as far as my Turkish knowledge goes =( Maybe someone a bit more expert-like can help me? =D

 My attempt:

I want you to trust me.   I really like you very much.  I am only together with you, there is no-one else.  At this moment there is only you in my life and onlywill be.

Wait for any correction though.
