Unless he's actually divorced or has served her papers and begun divorce proceedings she does not "look foolish" because he really is (legally) with her and not with you. He may currently spend more time with you and have sex with you, but legally he's married to her so he's more "with her" (legally committed, had more years, more sex with her, etc...) than "with you." At this point he has no committment to you and because of this there is more of a chance that you are temporary.
If a man really wants to leave his marriage he will do it regardless of his wife's pleadings and concerns with the children. If your boyfriend is serious about ending his marriage and being with you he will go to an attorney and have her served with papers this week. Anything less is an excuse.
Also, you mention him having had other affairs prior to you. It may be that his wife is used to him having serial affairs and she sees you as just one more in the series.
You mentioned on one post something about everyone over 40 having had an affair. Logically that doesn't hold even though I do think there are a lot who have, or have even had "near affairs."
There is no arriving, ever. It is all a continual becoming.
