There are two ways out of this relationship:
1) Break up with him and hurt him a little.
2) Keep 'going out' with him, but and you will end up breaking his heart once he finds out about your next lover (because there will be another one, sooner or later.). Then you hurt him A LOT.
Your choice sweetheart. I wish There was an easier one to pick.
Your friend,
