Feelings are kind of a pain in the Arse, aren't they?
Nah . . . they are what make us who we are. It's healthy to have them, and healthy to relase them when it gets overwhelming. The KEY, however, is to not make any DECISIONS based on them. It's imperative to do thinking, planning, executing.
Put more simply? OK to bawl into a bathroom towel at 2am, with the fan turned on so your wife doesn't hear it (true story of what I did in my sitch, lol). Just don't be drunk-texting your wife, or initiating R talks with her, during those times.
