In addition to what Kiechi has said (which is all true) I would add the following: Have you actually dated this young man? Because you know it is unethical to have done so and could end up costing you your job. Dating a student would indicate a very large lapse of judgment should your husband decide to divorce you, and therefore may jeopardize your relationship with your son should a custody battle ensue. To me, no romance is worth that. Work on your problems with your husband until they are resolved in a responsible way, but stay away from your students.
