there are plenty of problems love, support, and teamwork can't fix

to imply that love, support, and teamwork are not always what is needed to fix a problem. and that the solution is elsewhere.

but at least when it comes to problems that affect the family and the relationship, without love, support, and teamwork nothing can be fixed. only if you have love, support, and teamwork then you can find a solution. they are a necessary condition.

i think in the further discussion we reached a common understanding that this doesn't mean that love, support, and teamwork are sufficient. they don't make the problem just go away. sometimes the solution requires further action, or outside help. nor does it mean that the love and support of one partner can solve the problems of the other on their own, but rather it is the process of collaboration and consultation of the partners with each other combined with love and support by both that enables the finding and implementation of a solution.

one thing that may have lead to the confusion is that to me, the teamwork part already implies that there is more work being done to solve a problem. love and support alone can help address a problem without hurting the relationship further, but teamwork then makes it go away. to me it implies all the work being done to solve the problem.
