Wife moved out today

Hi, I've been on this website for a couple of weeks now and am really confused and devastated.

My wife and I have been together for 17 years, 12(well, on 12/11 it will be) of which we've been married.

A lot of our problems started 4+ years ago when I was hurt at work and needed neck and elbow/hand surgery. I was off work for 3+ years jumping through the work comp hoops. In that time, I became recluse and insecure. I shut out my wife because I didn't feel good about myself therefore alienating her. I love her and consider her my soul mate so this was obviously not typical behavior. I also was drinking a lot because I was depressed and being the wonderful person she is, she tried to build me up to no avail. Fast forward to now and I'm working as a temp in a crappy job which hasn't helped.

She left me on 11/9 and moved in with her mom. She has rented an apartment and move more stuff out today.

In the beginning, I left her alone after I talked to her the next day of her leaving me. She said we were done but I wouldn't hear it. Over the course of the next week, I left her alone until that Thursday,and then I called and left her a message. I noticed on T-Mobile there was a lot of text messages for one number and it started 3 weeks ago (at that time) when she went with some of her friends for a weekend away. I freaked out, had one of my friends call the # and it was a male. The next morning, I called it and sent her a text with the # stating I hope he is worth it and that she broke my heart. I actually talked to her that day and she said he is just a friend and that she isn't doing anything wrong. Now I'm not naive, and I realize this isn't a good situation but I didn't make a big deal about because I knew it would only push her to away.

We decided to separate and she told me that her plans were to get an apartment. That was on a Friday so I left her alone on Saturday. Then Sunday she mentioned stopping by so I text her like an idiot. I had my friend come over Sunday night and by the time he left, I was wound up. I woke up at 4 in the morning and sent her a text basically stating at the very least she was having an EA. That we were still married and that our wedding vows obviously didn't mean a thing. She ended up texting me back and forth and decided to meet me at our house on Monday night. We actually had a good conversation and ended up going out for dinner.

At dinner, she actually fed me some of her food which kind of threw me off but I could tell she was still mad at me. She spent the night in our other bedroom and cleaned up and did some laundry the next morning. I left her alone on Tuesday, and then I received a call on Wednesday that my mom was sent to the ER so I called her. She was luckily up here and not at her mom's house so we went to see my mom. My mom is battling stage 4 breast cancer so the news we received on Wednesday was bad.

My wife dropped me off that night and went back to her mom's house. I picked my mom up on Thanksgiving and brought her and my dad home. I let her get some rest and spent Thanksgiving at home alone with our two dogs. I talked to my wife that morning and actually Friday, Saturday, and today.

She answers my calls and text messages but I'm still devastated. Five months ago when I found out my mom had breast cancer, two weeks later we found a lump on my wife's breast and a couple of weeks later she had it removed.

We've been through a lot the last 4+ years and I know I need to giver her space which is what she asked for but I'm not sure if it isn't too late. I know I need to concentrate on myself and be there for my mom and dad, but I'm so broken with my work comp situation plus all the other things.

Sorry for the long post,
just don't know what to do?
