So my wife wants a separation. Keeps saying she doesn’t want a divorce. Wants to move out into an apartment. Should I just let her and if I do and we move into divorce mode how does this effect things?

Edit: I feel like a little background info is needed. She already had the affair and has been in recovery mode. Other guy didn’t pick her he chose his wife lol. We have kids and I do love her. She has mental health issues for sure but it is what it is. She breaks down crying regularly telling me sorry that she’s hurt me so bad. She’s really depressed about ruining everything and everyone’s lives. Her words not mine. She’s a mess honestly and due to her behavior and other things I could easily fight for full custody (never would that’s their mom and I’d only go 50/50) and I could definitely not have to pay spousal maintenance. She’d barely have money to do anything if she only got child support and her wages. I’m pretty much the only person taking care of the kids sooooo ya.
