I believe kovacs loved Ortega but she already had somebody and she may never get past him being in her bf’s sleeve and once her bf is returned to his original sleeve there was no place for him in her life. A case of letting go of someone you love because it was the right thing to do. He was willing to blow his own stack for her to die for her. So yeah he did profoundly love Ortega and they were great together on screen. So much undercurrent emotion in their scenes you could feel it.
