U-turn, big weekend! it sounds like you are ready to do what is right for you and your children. Feeling like you are acting with ingegrity and staying true to yourself will be important for next steps. I wonder if you step back and let w take whatever steps she needs to and you just work on formulating your own plan and boundaries. And see what comes.
I'm sure there are others here who will offer you the right advice and guidance! Me I'm just here to Maori (indigenous people of nz) " Awhi"you (have you back in a friendly way/support you through, prounced A-fee) and give you lots of here is another one Aroha (love)! (Pronounced A-ro-ha).
Btw I wasn't talking about getting your sexy back for another woman... Just thinking about for me when I'm feeling good about myself and feeling like I'm making decisions and in control of myself in my own life, I start to carry myself differently, I get my sexy back, I guess it's the personification of detachment. I'd like to imgaine you with your wife, showing her your sexy, you being completely in your own skin and loving yourself, completely confident in the place you stand. These are challenging times but your sexy is in there somewhere!
Congrats on your student.... That is a credit to your teaching and coaching. I hope you are super proud of yourself. Standing ovation and my applause hope you can hear them up there!
