I was with a man for a couple of years but i broke it off as he's not Christian. Really sweet, kind hearted man; he's been going through a rough time mentally and we have maintained a friendship. My problem is that when we first met i wasnt Christian, and we shared an active sex life. Although obviously now I've verbally set boundaries, i find its still a major temptation, and we have no mutual friends so I can't exactly ensure theres always a third party present. I feel almost a sense of responsibility for his mental health (i know, i shouldnt) so i would feel bad cutting off all ties with him. Can anybody provide some advice for me on what to do? I'm his closest friend but I'm also worried about giving in to temptation.
