I have no advice or experience in these matters, but I did want to come on and offer you support and a great big HUG! Remind yourself that you are loved, that you are worthy, and that some day this will all be a distant memory. Wishing for you to find a small bit of happiness somewhere in your day today. Keep holding strong and remember to let go of those expectations of both him and his family (well, anybody for that matter) because we all know that expectations lead to resentments and it's just not worth our energy to put that focus out there. Wasted time that you could be using to better yourself and your children with. Sending you lots of support today!
