I'm working on a short story in which the protagonist is a 35 year-old male. He's been living with his girlfriend for a few years. They have recently split up and he's moving into the basement of his mother's house. The break-up occurred because of some behavioral changes (maybe delayed PTSD). He's now dealing with some grief, shame, and anger about an abortion an ex had 15 years prior. He was the father and he advocated heavily for the termination of the pregnancy. I want to capture how his feelings are being expressed and seen by others. Can anyone share some thoughts on how his actions might look to a girlfriend as he begins to isolate or or become easily annoyed. The character has gone to 2 therapy sessions in the recent past, but stopped because the emotions felt too overwhelming to him.
