It can be very hard to recover after an affair. Especially by one that was done by your husband. Some tips that I can give you consist of the following. First, your husband needs to gain your trust again. You can talk to him about your fears and your feeling in regards to him spending time with other females.
Try to put it in a way that he will understand. Try telling him that you have forgiven him for the affair but still have trouble trusting him and that you prefer that he decrease the time that he spends with females when you are not around. Of course he cannot exclude work female, but as far as other female friends or associates, he can. Tell him that you have anxiety regarding this, and that you need to work on trusting him again.
As your husband, if he has had this indiscretion in the past then he should be open to you request. Also, you may want to consider personal counseling for yourself to work through some of the trust problems that you have. If you want couple's counseling may also help in this situation, to assist you in trusting him again, and work on his gaining your trust again.
