Actually, I think it depends on your thoughts first. Do you still care about him? I don't care, and then you can do what you want. It is understandable to turn a blind eye, or think that he will no longer sleep with him, or naturally ask for a divorce.
But if you still care about him, don't take a blood test yet. His admission that he is a prostitute shows that he doesn't want to lie to you. As for why he doesn't want to lie to you, there are two possibilities. First, he thinks that the relationship between two people should not be derailed, so he still cares about you. Second, he thinks he doesn't even want to lie to you, so he doesn't care about you anymore.
There are two reasons, one or two depends on your own observation of him at ordinary times. By the way, when observing a man, don't act as if you are observing him specially, so he will think that you have imprisoned him, and even if you have feelings, you will want to escape.
If it is the first reason, you can forgive him, which will also make him feel that you are considerate, which will increase his guilt and have a positive effect on him when he wants to do this kind of thing in the future. After all, what man doesn't do such a thing.
If it is the second reason, and you don't want to give up easily, then use your self-confidence but not pride, self-love but not arrogance, and express your love with actions, needless to say too much. Because he admitted it, but not to end your relationship, so you have enough room to work hard. Believe in yourself, come on! ! !
