Heather, I'm glad you had two people that you could talk to about your situation. Actually, the woman at your work place could most likely give you more insight into how things played out for her. It would give you a better understanding of what happens w/a mlcer hooks up w/op. I wouldn't rule her out as a friend as she did nothing wrong towards you or your marriage. Sometimes God puts people in our paths for a very good reason, i.e. to listen and be supportive.
I'm also glad to read that you met w/the homeschool mom. Another good example of support and I have to agree w/her...why now raise the questions about your youngest daughter's schooling? Of course, he's lashing out. You left him and you were suppose to stay right where he left you...back in Ohio in the home you shared w/him. He thinks you abandoned him, but because he's not thinking rationally, he's the one that left not only you, but the children, home and pets. Allow him to stomp his feet and eventually when he sees you aren't going to be a party to his drama, he may very well settle down.
Well, I can see your D20 has left no doubt as to the way she feels about her father. He's lost so much in the way of respect from his children.
I do hope you are feeling better today. I hope this coming week will be far better for you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
