Hang in there Pommy. I'm glad your daughters are so mature about this whole thing. I always feel like if my kids are okay, then 99% of the problem is solved. I can deal with the 1%.
You're hurting, and it is absolutely normal to feel that way and want to express that hurt. Although I do want to caution you that he may not feel guilty about the things that you think he should feel guilty for. He has his own version of truth, remember?
Bottom line is, you said what you needed to say. Keep doing what you've been doing, hold your head up high, as hard as everything is with the current lock down....you will be okay! When you're struggling and feeling down, we are here for you. (hugs)
