Will you marry me? my angel

Kız arkadaşınla gidiyor-
Kız arkadaşına gidiyor- if you meant "going to his gf"
or:
Kız arkadaşıyla gidiyor- if you meant "going with his gf"

I think "ne ioldum" means simply "ne oldum"
"hayat bu ne ioldum degil her zaman ne olacam diye dusunmeli"- Life is not about thinking what I've become, but you have to think all the time what will I be.

I'll try but it's really awful Turkish as CarGirl said:

I came for the whole day today, I told you today I came for you to talk about everything through (not sure, trying to make sense) the computer, but you weren't there, why? The reason I was mad at you was because you don't trust me my love, I don't know what someone has written to you but the only thing I know is that I love you very very much and after all that time you should know me, you know how much I love you, for you I've even completely ignored my family (disregarded them), I want you to trust me already, do you understand?

See if it makes better sense:

Şimdi daha iyi anlıyorum ki,
(Now I understand better that)
Nefes almak değilmiş, yaşamak.
(Life is not breathing)
Ateşlerde yanmak gibi bir şey,
(It's something like burning in fire)
Seni severken, sensiz olmak...
(While loving you, to be without you)
