I'm in a real jam here, fellas, and need advice.

Following up on my previous post from a few days ago, I have my daughter visiting for a week after not seeing her in person for a year and a half, because her mother took her to live in another state with her while I came to the one I'm in now to look for work after getting out of the military. You can read some of my other posts on my profile for the meat and potatoes of the issue, but I'll recall some of the big issues as to why I don't want my daughter living with her mother:

  1. Her mother is emotionally unstable
  2. Her mother is financially irresponsible and kept spending all of our savings on 'plans' to strike at rich that never panned out and left us just above destitution while I was breaking my back with 50-60 hour work weeks.
  3. Her geriatric narcissist parents also kept charging her an arm and a leg for rent, which is why she kept spending all of my money because they took hers and she wouldn't let me try and save anything to them to get them to stop because she didn't want me to 'rock the boat'.
  4. Her adoptive special needs brother is borderline pedo
  5. Her parents' place, where she lives, only has enough space for my ex, her daughter from a previous relation and my daughter all share a room that's basically 10x10ft

Here with me, she'd have her own room, better schools, real food that isn't predominantly precooked or takeout and a chance to grow in an actual loving household. My ex knows all of this, but because of her own issues has always fought with me on letting our daughter live with me, and so she has thus started putting down roots there. She's about to start kindergarten in August, has friends and hasn't stopped saying she misses mommy and her 'home' since she got here three days ago. I busted my ass to get a week off work and between spousal support payments, lawyer fees and other bills managed to save up enough to be able to have a really fun time.

I still want her to live with me, but is that just me being selfish? Me not wanting to have to start my life over again alone? I'm going to be honest, the thought of that little girl needing me to still be around has pulled me out of many a dark place throughout all of this, but I don't want her to be crying about missing people and being sad in the bargain.

What do I do? I feel like I'm wrong for wanting her to live with me when circumstances have led her to be happy living there but on the verge of crying when we get to facetime because she misses me and wants me to 'come live at my house with my mommy.' Believe me, kid, I want to, so badly. I wish I could go back and keep all of this from happening, that I could just snap my fingers and things be back the way they were.

FUCK! Just fucking FUCK!! This week started out so great, but now I don't know what to feel.
