Sotto, You sound very grounded and I like the fact that you are going to take the time to heal before you consider dating again.
Your social calendar is a busy one...but be sure to carve out some "me" time to rest and recharge your batteries. I do think it's a wonderful idea that you become a facilitator when you are ready. You will do well in that area.
I'm sorry to read that some of your friends are having challenging times right now. I do hope that things will get better for them. As for your h, you sent him birthday wishes and you did it from the heart. Now it's up to him to chew on that kind gesture for a while. He may not respond to you at the moment, but trust me, he will say something about it later on. I'm glad you didn't allow his silence get to you.
I hope you have a great weekend.
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.
