Someone could tell me what you get relationship points for and what will happen if it goes to zero, because the game doesn't explain it.
Not only can your relationship points go to 0, but they can go into a negative integer. This doesn't necessarily result in a game over, though. This just means that you go into the angry wife playthrough. Many of the same events will occur but Anne's attitude will be totally different. She will be cheating on you and cucking you rather than doing it for your amusement. For some, having a pissed-off wife cheating on you is a fetish. For others, it is a source of irritation. If you want her to cheat on you and cuck you you need to alternate between insisting she flirt with other men and then tell her she can't sleep with them. You need to refuse to fuck her when she asks. You need to be scornful of her efforts to tell you about her individual adventures. You need to tell your father to accost her in the shower without her permission. You need to cheat on her yourself. You have to do a lot of asshole things to get to the angry wife playthrough, but the number of folks on this board that find themselves in it by accident is staggering.
To get the happy wife playthrough:
- Don't push her too hard in the beginning of the game. She is still being trained.
- Always sexually service her upon request.
- Lend her your ear early in the game. Later in the game, she will not be as apt to share her experiences. (warning, this may give you the cuckold trait but you avoid this at the resort by sacrificing 1 measly relationship point).
- If you must have sex with other women, don't make one of them her best friend early in the game.
- If you have a choice between having sex with another woman or peeping on your wife, peep on your wife. She likes it.
- When she asks to fuck someone, be magnanimous. This is a positive development. If you keep refusing, she will get frustrated and do it anyway without your permission.
- If she admits that she is hot for a guy from her past, be a good sport and let her fuck him while you watch. Also, she will like it if you join in for a devil's three-way.
- Participate in swinging. The fact that you are having fun too pleases her even though it also makes her jealous (cuckquean trait). She has both "good" jealousy and "bad" jealousy and you can get the former by participating in swinging and 3 ways (will result in "swinger" trait).
- Don't refuse to let your wife practice exhibitionism. It is her fetish. If she says she isn't interested in having sex with someone she is teasing, don't insist.
- Don't let your fucking dad surprise her in the shower. It is a violation and will send them both down a bad path.
- Refrain from having sex with her mother after you have an unavoidable fight because of a tactless comment.
- If you find yourself on a golf course teasing a father and son duo, either let her perform sex acts for your viewing pleasure or perform sex with you for theirs. She is an exhibitionist. Telling her that you would rather go back to the hotel is a bitch move and the game will punish you for it.
There are other things that can hurt your relationship with her, but in general it is safer to have your own sexual adventures later in the game when you two have already had the conversation about being able to have sex with other people without prior permission. Don't put up with your dad's bullshit as he is trying to steal your girl like he always does. Always be encouraging to her when she is pushing the envelope and don't be the pushy one. Don't recriminate her for doing what you wanted her to do in the first place. Do all these things and you will enjoy the happy wife playthrough where she is fucking around for your mutual enjoyment and you are free to do the same.
