Atsbaby's posting is spot on. By using the "I" word, you aren't pointing fingers at what he is or isn't doing. You are letting him know how you feel about things.

I do agree that your S14 is old enough to have talks w/his father about how he's feeling and being treated. Encourage this bonding and then step back a little and see how it goes. You don't want to come off looking like your h's "mother" in all of this.

Stating that you are interested in doing something and inviting him is a good way to test the waters. It gives him the option of whether or not to go w/you. If he doesn't want to go along, plan to go on your own.

Good luck and keep your expectations low.

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.
