I'm so sorry that your going through this. Take the time you need to heal, put your brave face on when your with your daughter and then give yourself some you time to express yourself. Don't you worry yourself, us mothers just always find away to survive, we are like a lioness, protecting our little cubs. She will watch and learn from your strength and admire the ability you will muster up to rebuild for the both of you. Sending you so much love.
Is your family able to help watch your daughter? Maybe you can look for a full time job now and they came help or look for new daycare. As much as it sucks it’s happening. You can do this! Sorry he’s an ass
You’ll get through it! It always feels impossible when it first happens, and there’s no pre warning it just slaps you in the face, but you’ll get through it. Honestly your daughter will see it as the best sleepover ever with her favourite person! Take your time to build yourself up again, you may be able to qualify for free nursery hours which could help you work more, also get him on child maintenance. I really wish you and your daughter all the best, it’ll take time to get where you want to be again but it will all be done out of pure love, not built on lies and nobody being able to take it away from you and that’s the best thing you can have x
That pain sucks but know if you need a listening ear I'm here
