I get why you are saying this - because it would move Rock forward rather than being eternally stuck.
But I don’t think that’s a good way to do it. I couldn’t imagine the pain or damage that this situation might inflict on a new girlfriend. Imagine if 6-12 months down the track, new girlfriend found out that she’s been used as some sort of cheap tool for Rock to try and solve his co-dependency issues.
I’m also sure that nut-job ex-wife would easily manipulate this new relationship. She’d pretend to want Rock back - he’d burn bridges with the new girlfriend, come crawling back - and then ex would laugh in his face. This entire marriage’s dynamic is incredibly unhealthy, and there would be all sorts of attempted manipulation from both sides if another person appeared. Plus, Rock is so co-dependent he would only take a new girlfriend to try and manipulate his ex-wife back. No-one coming into a new relationship deserves that!
Step 1 - long term professional intervention to detach and work on co-dependency issues Step 2 - (only after step 1 is a success) - find a new girlfriend
