How about, the players like us, giving an option after we know that our partner/avatar is pregnant. Abortion or Take responsibility(man avatar) ; abortion or tell to your partner(woman avatar) the story of the game based on our (players) choice. And the game will turn a complete visual novel simulator. XD
I've seen it in other games, and here is where things become crazy in Influencing... What if your partner wants to keep it, you don't want it and you're not dominant in this relationship? What if your partner don't want to keep it and you want it? See? There is a lot of things that could happen! I have a draft around those ideas! But still a lot of things to be decided!
Here's my idea: if your avatar is a woman, there's always a 2 option after selecting 1. If you get pregnant, 1st option appeared: abortion or inform your partner; if we choose the abortion in the first place that's it. But if we choose the "inform the partner" the result of our choice are based on their "personality traits". If the partner are scum, he will deny and suggest abortion, then another option appeared: "take responsibility" or "abortion". If we choose "take responsibility" we will witness the changes on her body figure, our character turn to single mom. But if the partner is willing to support, another option is appeared: living with your partner or take responsibility. If we choose living with partner, we will live on his appertment, if the partner is married, his wife will leave on apartment.
If we play as a Man, we will have 2option only: ask abortion or take responsibility, if we choose take responsibility, our partner will live on our home.
I know this suggestion is kinda complicated, but I do not rush you nor force you to do it. I'm just sharing my idea :)
