Boyfriend received blowjob from a crackhead

Hi guys… this is not a made up story. This is real. two nights ago I found a very disturbing video of the guy i have been seeing for over a year, receiving head from a crackhead on the street. In London. This is really bad. That same evening he met up with me and was intimate with me since it happened. The worst part is that he also lied that same evening after he finished doing the deed he messaged me saying someone had jumped on the train tracks and that was the reason for his delay… this is almost like a movie. How could he pay a desperate crackhead to give him a blow… and then go inside of me, how irresponsible, unfaithful and no values this guy has… But on top of that lying about a random suicide just to cover your lies is incredible. I told him I would give him oral sex once we were in an exclusive relationship… he chose to pay some desperate stranger off the street. He will never receive oral sex from me. That is his loss. Also let me please mention he is Muslim and his family is religious, he feels proud of being Muslim. This happened on the 4th of February. So three weeks ago. I can’t speak about this with anyone… Any advice?
