This is not a subject to be joked about or taken lightly, but seriously, you have to question the mental health of someone in his position who would choose someone as vile and hideous as Paula Gretzky for a "life partner".
I would beg thinking that there are some VERY serious issues that he has to deal with and being married to "party girl" with her past is going to be part of the problem, not the solution.
Reading between the lines, it is very possibly substance abuse - given that he talks about "self improvement", which is much more telling than simply "getting healthy", the more usual euphemism.
You never cease to amuse me sir, vile and hideous - funny shit.
I too wish DJ well...
