Managing the guilt of giving up on your marriage

Here is the full backstory https://www.reddit.com/r/daddit/comments/1skxsif/burnt_out_dad_getting_a_divorce/ TLDR; I was feeling like a full time dad with my wife playing pickleball or sleeping all the time. I do not believe there was an affair going on.

Wife and I are going through a tough time right now. Since my post last month my wife and I had decided to try discernment therapy, (we only did one session out of 5 and she cancelled the rest). I also agreed to individual therapy to help with my emotional outbursts and communication issues. Well last Sunday (5/31) we had a fight. She said basically everything she doesn't like about me. I was so overwhelmed that I angerly yelled "I need space" and walked out of the room. My wife said this made her feel unsafe and she told me to leave or she is calling the cops. To complicate matters we live with my in-laws so the house is in my FIL and my wife's name. So I left as I did not want the cops involved and I figured they would ask me to leave to just help diffuse the situation. Over the past week I have been living out of a hotel and touring apartments and I found one I really liked. Of course just as I applied my wife wants to get back together (this was Friday).

Difficult thing is I have been going back and forth over the past week on wanting to make this work. Over the weekend its been even harder as I spent Saturday afternoon and Sunday back at wife's house to see my son and help her out since she taking the majority of child care right now. I did maintain boundaries on still sleeping in the hotel. I think the weekend of helping out my wife has stirred up a lot of feelings of past memories and guilt of quitting on this marriage. I feel bad for my son and us not living together. I just know that I cannot live in word where if I get a little angry and leave the room my entire life gets flipped upside down.
