Is he really flirting or loves me?

He is my next house guy. We knew each other from some yrs. But became friends from 7mths. On 1st day he said he loves me but i refused as i knew he was a flirt. 4yrs back he had a break up frm his true luv. At some corner of his heart he is still depressed. He nvr again said he loves me. He says i'm he bst frnd, he shares all his feelings wid me, even about his girl friend. He watches pron & i'm invited to accompany him. He pressurised me into physical relationship. After a long time i gave into it. Many times i asked him based on what v r having ? for this he just says some relationship dont hv name. I feel he is having some feelings towards me but not telling out as i may refuse or break up?
