WW in MLC affair and I need advice..

[Natash]

Good morning friends, I am looking for some advice. I have read that a H needs to show his WW tough love. I also understand I need to detatch and let her go (am working on it). My delima is choosing when to use which one? Should I use let her go over tough love? I know for myself the tough love will be something I have to work on. Right now W is still sharing our Master Bedroom. I feel like if I put my foot down and say enough is enough, you need to sleep else where before moving out that conflicts with the let her go approach. I should have kicked her out right after BD but did not want to rush to any decisions and did not want my girls noticing. I now have a bed setup in a spare room and feel I need more space to be able to continue to detatch. I'm also getting tired of being woken up at whatever hour the W crawls into bed. I think the core issue is I have not been able to come up with any boundaries to enforce while WW is still home (other than calling her out on any disrespectful words/ actions towards the girls or myself).
