Oh I know the story revolves around her and he is simply a plot device. I never expected a revenge or even a renaissance route for him. My personal preference is to break up with him asap. I'm simply speculating on how a renaissance route could work and pretty much everything you said reinforces my point. Her not telling him everything, having to accept conditions, him needing her more then she needs him and willing to accept whatever crap he has to endure so she'll allow him to stick around all contribute to him being a pathetic loser with no self respect and I'd hardly call that experiencing a renaissance and definitely doesn't count as him 'winning her back'. If anything he's probably at the lowest point in his life and is just accepting it so he doesn't feel entirely useless and like he's lost everything. Everything described above could easily fit into any of the sharing/cuck routes that are likely to dominate the endings. You could just stick the BF into any of the other major characters endings as a side note saying he couldn't bear to be away from her so he accepted her being Jeremy/Michael/Taxman/Sergey/etc's personal whore and he was lucky enough to be able to support her financially and emotionally. It's impossible for him to maintain any dignity or respect whatsoever as a man. Again I realize it doesn't matter if he wins or gets revenge or maintains respect or anything even slightly positive whatsoever, I'm just saying a renaissance or win her back route just seems super far fetched at this point and I have trouble seeing it come to fruition.
