Oh well, if you're confident enough with yourself then no need to worry about your husband.

One more advice, don't rely all your needs with your partner as it's always better to have your own (money & job) just in case of unexpected separation and/ or any unforeseen circumstances. If your husband have an affair and you have caught them, don't do same mistake as a sign of revenge; instead, focus and enhance yourself to show them that you can still live your life the way you want without commiting any wrongdoing from your part.
