I have to agree with Karrie. If the relationship between you and your bf is serious and you think there might be a future, just leave Leo at home while you are visiting. While I know you love Leo, it is their house and just like you wouldn't want them bringing their cat with them to visit you, I don't think it's fair to expect them to just accept Leo. In the end, the rivalry you'd spawn isn't worth it. Lep will be fine for a few hours by himself.
