She is in IC but I think they are working more on her childhood and the why then how to help me. Makes sense as I should help myself I suppose.
My W signed a release allowing her IC to talk with me. In our case, W's IC became our MC, and the release allowed anything my W said in IC to be brought into MC sessions, at the C's discretion. You can't do that, but you can ask for the release and ask for periodic joint sessions to keep you up to date.
What help do you want from your W? What will you do if she doesn't or can't provide that help?
You aren't doomed if your W doesn't help you. Healing is something you do on your own behalf. You don't have to do it - healing is necessary for thriving after being betrayed, but you don't have to do it. Your W can't make the pain go away.
Do not count on your W to help. The best she can do is change from betrayer to good partner. That's her work to do, and she's the only one who can do it.
What you do now is for your future. Bringing an ap - and spouse - to your wedding is an egregious boundary violation. Revealing an A after you revealed something deeply personal is a terrible violation. Texting a current ap while talking about a previous ap is a terrible boundary violation. They're in the past, though. Now your best bet is to exorcise the residual thoughts and feelings. You can do that, and you'll be glad you did. But you don't need your W's help to do it. A good IC, yes; your W, no.
You heal you.
Your WS heals themself.
Together, you heal your M, if you both ant to.

Your W may be in the process of becoming a good partner. Time will tell.

I urge you to avoid living in the past. Yes, your W's As have brought immense pain into your life. She victimized you. But you don't have to take on a Victim role in life. It takes work to stop ruminating about what she did, but her As are about her and her issues, not about you or any issue with what you did or did not do.
Even if she thinks she cheated out of anger at you, her A's are not about the real you - they're about her image of you.

IMO, the people who do best after infidelity are those who take responsibility for themselves and take advantage of the options open to them. It's the people who say to themselves something like, 'I'm not going to let this ruin the rest of my life. I'll do _____ instead.'
It looks like that's what you're doing, so you've made a good start on healing, IMO.
