Don't do it. He will remember believe me, but it will fill him with guilt. You contachim, it eases his guilt.
Your title drew me in, my W has not exactly had affairs, but has had 3 one night stands, twice with 2 of he same men and possibly more. I've only literally detached myself (i'm in newcomers for full details) and it was tough. It's taken me 7 months and I wish I'd got here sooner. I became fed up with my W and her behaviour and don't want to be associated with what she has become, she can figure it all ot for herself.
