Here's a choice:
Get acquired and then leave as soon as you can walk away with a mountain of cash.
Act like you will stay forever. But leave in a year. Leave money on the table if you must, but grab a huge chunk of it first.
Do not tell anyone about your plan. Not even your wife.
If you tell your wife how you feel, she will likely:
- Lose respect for you - start hunting for a better provider (Don't be surprised if she starts staying out late and you find she cheated on you)
- she will work to limit your access to your children.
Suck it up for just 1 more year. Make your decision (and make it final with only input from your closest friends and parents/brothers/etc)
Hypergamy is real. Do not listen to the crap here about therapy or sharing this with your wife. Mark my words, you will be in a more fucked up state whem she leaves you and you are broke too.
