You need to set boundaries with him. I have been, recently, in a similar situation. Even if it’s hard you need to talk to him about the akward or uncomfortable things that have been avoided in this. You need to let him know that you still have feelings for him and that maybe you need a little more space to clear that up. I’m guessing if he is still sticking around he may still have some feelings for you too. My personal solution to this is to talk about it because in the end both of you will understand each other better and get these unneeded stressors off your chest, which will also hopefully help you move on to something new and hopefully better, not saying he is a bad guy, but if it ended there is probably someone out there for you that is more compatable. I hope this helps.
