He already is heading towards nice boat ending and at this situation harem ending in only one good solution while another solution will be losing both girls.

Also it will be hood test on how they love him as the girl who agrees to stay even if she has to share him with another is really worth keeping and in she will leave that is just for the best.

In that situation I would put ultimatum to both girlfriends that I love them both and wont leave or select any of them. If that ok lets stay together and those who don't like it can leave.
I am quite sure that they both will whine a bit, but eventually agree because it is not that they will have good choice.
