Okay, this has been tough, very close, all pointers welcome?

left wife two months ago, no cheat / abuse. I was neglectful and a jerk. We spent last week at her parents, meeting to work it out. I work far away and it was the first time seeing each other in a while. I was wrong, I admitted it and apologized. weeks of suffering and waiting. I did a 180 and changed my neglectful ways. She has agreed to work it out and will be coming to see me again for another week on sat or mon. She is still very back + forth though, its easy to tell. I am always waiting for calls. She says we are fine and gonna make it. I wonder how long till shes back to her loving self. and how long i have go through this.
She did see another guy briefly, after weeks of begging to work it out. She was hurt very badly and alone, he gave her all the attention I should have. She stopped seeing him but was hurt (felt bad) we live aways apart and will for rest of summer. She is supposed to start coming here every other week. Any advice on how to handle this? What should I be doing

Remember that before she was a wife, she was a person. Treat her with respect in all matters.

Break with the past--see if you two can agree to not bring up the past in your discussions and start with a clean slate. The history has hurt both of you and it should only be talked about in the context of healing hurts, and for no other reason.

It takes a big man to realize his shortcomings and an even bigger one to go to the trouble of changing. You have my respect and admiration.

But for you it is the admiration of your wife that counts. Be sure you make some contracts, like she can speak freely without fear of reprisal when she feels neglected, and you can answer freely, if you think what she says is a bit over the top. Keep the lines of communications open, and realize there are such things as comfortable silences as well.

Back to her loving self? Not likely. This is a new game with new rules, and you and she need to work those out. You are 90% there but do not neglect the details.

I would only make changes you know you can 100% continue with so you don't fall into the trap of flowering her with attention then stopping it at a later date, that will only cause her to be more hurt and resentful.
I would also take it very slow, show her why she fell in love with you in the first place then stay that way, don't change.

slow down! take it step by step. maybe even throw a few counseling sessions into the mix. there has been a breach of trust, security, stability, and so much more. it will take time to process, and even more time to heal from it all. nothing is going to happen over night, let alone over summer. take it day by day, and realize there will be good ones and there will be bad ones.

I HAVE BEEN THRU SOMETHING SIMILAR MAYBE YOU GUYS NEED TO TALK THE TRUTH AND SEE IF YOU ARE REALLY READY TO WORK IT OUT AND MAKE THE COMMITMENT TO DO WHAT EVER IT TAKES TO WORK IT OUT ANG GET TO WHERE YOU ONCE WERE.MAYBE YOU BOTH SHOULD THINK ABOUT LIVING TOGETHER AND PUTTING WORK AND EVERYTHING ELSE ASIDE FOR A WHILE THIS SHOULD BE THE FIRST PRIORITY ONLY IF THIS IS WHAT YOU WANT GOOD LUCK

northing, the ball is in her court.
