Dear Dave

Just a quick heads up you may need to speak to an accountant about the tax implications re selling both properties. ie the smaller property is now your principal address so maybe for you no capital gains tax on that property, but your wife may have to pay tax on her half and then vice versa for the larger family house. Therefore your tax burden could possibly be greater.

As for your new romance, since i guess you have been upfront & both the lady you are seeing and your ex know about each other.  Enjoy .
