I am in a similar sitch as you my friend... I know it can be tough as all heck but I can tell you right now fixing yourself and saying "but she doesn't see it because she is not living in he house" tells me that you are trying to do things so she sees them and comes running back. This will not happen, I am on week 7 and I can tell you the ONLY things that have helped have been things which were truly just about fixing ME not about getting her love back.
You need to focus on fixing you, forget the OM and be the BETTER option. You were once the man she fell in love with, be him and BETTER again and do it for you. Because then even if she doesnt notice or come back you are in a much better place and won't repeat the same mistakes.
