Not. It's because the game is not finished. Anyway, like I wrote before, if you keep choosing the red, when you interact with the Martin, she will break with him. Only interaction will be repeating scene when they break off (2pm). Something like dead/missing stepdad who keeps appearing in basement orgy.

So, technically, he remains in the game, but only because, let's put it this way, progress of said game is lagging.
That's not completely true. If you make Cassandra yours, she will stop seeing Martin (except repeating breaking scene). So, there is no porch, no bar anymore.
