shortee, in my opinion, your personal journey is what it is. You can't compare it to anyone elses. The details of your H's infidelity are unique to your marriage.
If I understand correctly, there was not an immediate turn around for your husband, so you suffered extra pain.
10 months doesn't seem long to me at all. There's so much to think about when an infidelity occurs. So much to work out.
You're coping and doing the heavy work of R. No reason to be down on yourself.
Hang in there. Hopefully, your H can help you through the rough times.
