Ok Yeah... Here comes some 2x4s because I care and I believe you need one.
So... You have another person now who is ears and willing to be your shoulder, totally get it and yeah I've been there. Here is the deal... What have you fixed, how have you grown? According to your timeline you are leaving a M that was what a whole 3 years and came here to DB it and now you've inserted a 3rd party... So are you done? Are you really trying to save the M at this point... Were you ever really all in? I ask this not trying to be an a$$ bit to really get you to ask yourself where you are and what you really want... Makes no difference to me TBH but from this point forward what you want and where's you are headed is important to how you "DB" from here .... You can't save a M if you are gonna insert a 3rd party just as a WAS can't commit to a M with a OP
Questions you must answer before moving forward .... All in or all out the choice is all yours
