Guys, I need some serious advice,

So recently, things haven't been great between me and my wife. she found out I was attracted to her sister and had sex with her best friend. I know I am an asshole.

My wife is a good person, she came into my life when no one was there and she turned it for the better. Now, I somehow feel like I deserve better, just because she keeps reminding me how she helped me in the past, which is very demining. While, she has a good heart, but I never was able to connect with her on a deep level, I feel like she thinks of me as an object, not a real human with feelings with flaws.

Anyway, things got really ugly recently and we both found out some ugly truths about each other, however, we're sticking together for the kids and the greater good. We also have a very comfortable living together and we kind of like our life as is.

It's been months now, we barely speak or look at each other faces. We're like roommates, we sleep in different rooms and barely even see each other. If we cross paths, we look in opposite directions.

I know she hates me more than anything. We both know, that when the kids are older, we need to go our separate ways, However, for the time being, I wanna win her over and make her happy and win her trust again until we decide mutually to separate and do what's best for our kids.

Any advice on what kind of things I can do to give her interest in me again?
