First time posting. Waw and trying to repair

[Tyler12]

Here is my story.
I have been with my wife for 5 years.
M 1 year 9months.
We have 2 children together 3 and 10months.
Also I have 2 from a previous marriage which she completely accepted as her own.

I thought things were good until 2 months ago when I was told she is leaving me.
She is unhappy with everything and has been for a long time.
Shortly after I found out there is another man in the situation. I immediately started seeing a therapist.
Reading books and forums to change my issues.
Which I fully admit.
I did nothing to make this marriage work and I accept my responsibilities for my part of the failed M.
Where we sit now without going into extreme detail is that we live together until she can get the funds to rent someplace where she wants to move with the younger 2.
The older 2 visit every other weekend and live with their mother.
We have shared a bed a few times in the last 2 months and had sex for the last time 2 days after she told me she was leaving.
She leaves every weekend to go to where she is "happy" and usually with friends and the OM.
I asked her to be 100% truthful with me if they were having sex. She said no.
However like the rules state believe nothing they say. She is always texting.
Snap chatting and talking on the phone with friends and OM. It's quite painful to see and live with.
Right now I at the point where I don't care what she is doing. She has to follow her path.
And I being the grown up/ parent.
I have to be who I need to be for my children and myself.

I am 32. She is 26.

I find myself being much more happy with my life now that I am keeping myself busy and spending more time with my kids.
If or when she wants to be part of that.
Great.
Until then it hurts.
But I am happier.
Last night after returning from her weekend away and I listened to all she had to say about the fun she had.
I stopped her and explained how I felt about certain subjects and how they are hard for me to hear and cope with.
This last weekend she was away brought her to the point where she is probably more attached to the OM and at the same time told me that if I had been acting/living like I have been for the last 2 months over the last 5 years this never would have been an issue.
So while I accept that my change is not changing anything between us right now.
It has opened her eyes to the fact that I have changed and want to continue down the path I am going.
So I guess my question is What do I do from here?
Just keep on focusing on myself improvement?
Or should I add in trying to reconnect?
Or distance myself and hope she approaches me about reconnecting?
