Need Help before I blow a fuse.

[20&lost]

Had a decent day yesterday. What I didn't do and I now know to do is that when my W talks to me is look at her with loving eyes and pay attention. I have been so focused on the negatives for so long it is hard change your mindset and to be patient, very very patient and to concentrate on the positives. I did not see my W after supper (she was in a decent mood) until she came into the office this morning and she was in a terrible mood; had a scowl on her face. This is when I most want to engage but know I shouldn't so I didn't. Disengaging is so hard.....Does it get better with time? I have been GALing. Got my Open Water Scuba Certificate, which came in the mail yesterday. MY W maybe upset over this since both of my kids are certified. I had asked her three times over the last year if she wanted to but she found a way of saying no, even tho I think she really wanted too. Because of the kids it is something I wanted to do so I just did it. I have also started an exercise program (CrossFit) with my S.
Because my W and I work and own the business together, days like today are hard but I am keeping my distance because I know the only one I can change is myself.
