Serious GAL activities will help you enormously. We hammer them here, b/c we know they work.
Actually, I don't recall...any GAL from you, other than being with son, which is not what I mean by GAL.
Meet NEW people and do NEW things, or resume activities you loved.
Take a class, volunteer somewhere, find a new church -that your Xw does not attend--
b/c you are NOT an intact family so let her do the "single mom goes to church" routine...(which, btw, -and Kaffe Diem, this might apply to you--single dads who take their kids to church, GET HIT ON at my church...)
learn a language, study cooking or pottery or something wacky and different and out of your comfort zone
JOIN something...and GAL. Fill your "no son" time with NEW people and activities.
It's for you. But I cannot believe your Xw won't wonder what she let go of...
but you have to let go of her, for her to feel that you're not still holding onto her.
