OP, tough situation with many good suggestions so far. As I read thru the posts I began to wonder what if you could put together some sort of agreement or 'contract' that you both would sign and adhere to. Something that would limit each spouses liability to the other spouse's financial actions. Something that would be binding should a divorce become the inevitable end solution. Something like a pre-nuptial agreement except after the wedding. A post-nuptial agreement. I googled it and surprise, surprise, there really is such a thing.
I'm just an old IT guy so know nothing about any of the legalities of this. I began wondering what I might include in this agreement. Maybe things like:
1) n % of each spouse's portfolio is untouchable by the other spouse should the marriage dissolve.
2) Spouse #1 agrees not to retire until his portion of the portfolio reaches at least $nnn (specified dollar amount).
3) Spouse #2 agrees not to retire until her portion of the portfolio reaches at least $nnn (specified dollar amount).
If one spouse sees their portfolio value decreasing which will increase the number of years that will need to be worked and their partner's portfolio is increasing and gaining ground on that retirement date then maybe a lesson will be learned.
As far as investing goes I had my head buried in the sand up until 3 years ago at age 54. It started to dawn on me that I was getting closer to retirement and I had no clue if I was invested properly or how much I needed to pull the plug. So, over the past 3 years I’ve been reading investment books which were suggested by the bogleheads website as well as learning from their forum as well as great info from this one. Point here is that you’ve said that “The problem is she did not have hardly any interest in investing her money until recently” which I’m assuming means little or no investing knowledge. For myself, I thought how can I make intelligent investing decisions if I have no knowledge about investing? It's like thinking I could write quality software code without knowing the programming language. Not possible.
Thanks to modern medicine my DW is down to just a couple personalities, which is manageable
. I’m working at getting better at our conversations so that I don’t trigger the 12 year olds appearance. It can be difficult to reason with a pre-teen girl
. May or may not apply to your situation but how you word your conversation can help prevent putting the other person on the defensive.
Good luck!
