in love with a man I can’t currently have

Anna

For a year now I’ve been sleeping with a supervisor at my job, who also has a gf who he says he isn’t sure about and hasn’t been sure about for over a year now... he has told her multiple times that when there lease is up they are parting way... this guy has also basically confessed his feelings to me when I recently tried to break things off because I feel horrible for being this other woman and I want him to be single before we continue on... I have told him that if he truly wanted me and not his gf he would’ve left her by now but he claims it’s not that easy etc due to the fact of their lease and that he had a life with her for so many years... he has also told me that they keep arguing and he is sick of it... this man has opened up to me and we have such a strong emotional connection and a strong sexual relationship, I just don’t know what to do anymore... as in everything has been hidden for a year now
