So I'm dating a guy who is legally married but has been separated from his wife for a year. The reason they have stayed legally married is because she is in the military and he gets TRICARE through her. He's diabetic and currently in school. His jobs insurance is really bad so she agreed they would stay married so he can get his insulin until he finishes nursing school. I've "met" his wife, as in I've been there when she's picked up the kids for her weekend with them. She hasn't really ever said much to me besides smile. I really like him. Everything is just kind of awkward and it's weird to have a boyfriend but also call her his wife.

Edit: He doesn't call her his wife. He calls her his baby mama. I just say wife when explaining the situation and it's weird to me. He has two more years in nursing school. Once he's graduated and gets a job in nursing where he can get insurance that's when they're gonna get divorced. They just want his medical stuff taken care of first. He doesn't make a lot at his current job. The insurance would take a large chunk of his already small check and it's bad insurance.
