Ladies let me know what you think I should do

I found out on the 21st of this month that my husband who was away on business in Bangkok stupidly went to a brothel and slept with one of the bar girls there now I am happy that he has told me and didn't hide it from me but now I am questioning if I should be with him or not I have completely accepted the fact that it happened and that it was a one time mistake and he regrets it with his whole heart and he hates himself for it he has asked me to get us in to couples counciling so we can work through this rough patch in our relationship when he gets back on the 9th we will be having a very long talk about why he did it and I have already made an app with our doctor to get him tested he was tested over there but I do not trust them and I want to make sure he gets the tests done as I have heard of bar girls paying the doctors over there and getting a full clean bill of health even if they are sick it is a very money drivin place over there plz let me know what o should do as we have two children and I don't want to leave them fatherless and I don't want to lose the marriage and love that we have for each other but I am worried that he has done it now what is going to stop him from doing it again in another country when he goes away for business again I am worried I won't be able to trust him again if he does go plz let me know what you think thanks
