El gave indeed some great advice.

Thank you very much for that EL.

And I'm aware of the fact that this is great advice because I have done the same thing for the past year while he lived abroad and this worked really well for me as well.

The huge difference is the actual situation. I have let him come home, turns out I've made a mistake here and got sucked back in, so it is not easy to turn the situation again.

Please understand that there is a huge difference in an @home MLC'er and above all a clinging boomerang, the moment I'll be on my on again I have much more strength to draw the line where I want it to be. Unfortunately this will only be possible when he will be gone. Do not forget we are having 3 children under the same roof, I want it to end as smooth as possible, and avoid as much drama as possible. Very difficult with a manipulative MLC'er who wants to keep his "old" family close.

Your wording about I'm still wanting to control him and having a cake walk is quite harsh TBH.
But you can share your view on the situation. I don't want to control him, I want to get out of this situation in the most peaceful way as possible, although I'm aware that this will be difficult to achieve. This is unfortunately my nature, I hate conflict...and that is why I try to find some answers here, and I surely did.

Thank you all.
