This question is hard because there isn't much more information about your guys relationship.
Do you guys really enjoy each other's company? Get along well? Love each other? If so, that might be a few good reasons to stay, but then again, I'm not you and I don't know the story.
If you feel like it's dull, and things might be coming to an end, it might be better to cut it off so he and you could meet people closer to spend time with in real life.
Just some thoughts, I don't know.
