Again, you are getting VERY good advice already. Follow it!
Sit down and take real time to read it, then do your home work. You mentioned digging to understand more. I think you need to dig real deep to understand yourself first and foremost.
After reading your post again in more detail it reminds me SO much of my R about three years ago when our first D was 3. She is now 6 and I am divorced.

Looking back and knowing what I now know about myself in relation to NGS, sexual desire, boundaries, validation, etc I could have probably prevented things.
So I would give your sitch a good chance. But again, Do your homework! So many here don’t really do it at first.
When we say read through the welcome thread, yes we mean read very single post in all the links. In your case, make sure to read about validation and boundaries. Then move on to the books mentioned above here. Read all of them before your first therapy session.
