It is dangerous to keep having sex with him. You really need to stop and wait for 3 months and get tested for STI's and hope for the best, keeping your fingers crossed. At least you are finding condom wrappers so he is not having unprotected sex but still. You are not even reporting some amazing sex with him but just "good"; you can survive without it. As for friendship, you can keep him as a friend if you wish after stopping the boyfriend/girlfriend relationship; such arrangements can be made. But why don't you have other friends? that portrays an impoverished life; why so? when did you stop having other friends? How was it in the past? It was not always the case that you did not have friends, was it?
