I am so sorry that your wonderful news was spilled entirely too early. I am not making excuses for your son's father, but maybe he was so excited that he couldn't help himself. They do love attention any way that they can get it.
Please tell your son that it is still wonderful news and can be celebrated with lots of love and happiness even if his news was announced early.
Congratulations on the news and I hope all of you can enjoy the upcoming months ahead. Lots of planning for events and a baby shower. You will enjoy being a grandmother. I can't wait to hear all about your adventures with the little one in the future.
Life after the bomb is what people need to read about. Posters at the moment are in the eye of the storm and can't visualize what life can be after the dust settles.
Please keep posting.
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.
