There isn't a single, universally accepted term for a deceased boyfriend. You can use various phrases based on your preferences and the situation. Here are some options:
- "My late boyfriend" is a formal and respectful way to refer to him.
- "My deceased boyfriend" is another formal option, often used in legal or official contexts.
- "My boyfriend who passed away" is a more informal way to describe the situation.
- You can also simply say "My boyfriend" if the context is clear, and it's not disrespectful to the person's memory.
Ultimately, the best way to refer to your deceased boyfriend is whatever feels most comfortable and respectful to you.
