Hi, Loca, and thank you for sharing your question. It's great that you're trying to learn as much as you can about epilepsy. I think it would be good for you to learn what to do in case your boyfriend does have a seizure in your presence.
Here's another article on What to do when someone has a seizure.
My brother was once married to an epileptic; she had Grand Mal. She was eventually deported back to her native country because her father couldn't get medical coverage for her here. Meanwhile, my brother had to learn to watch for symptoms.
I once worked with a fellow in a high stress office whose seizure was brought on quite suddenly and scared the dickens out of us. But, the few of us who were close by managed to remain calm and, while a couple of people tended to him, I called 911.
Does your boyfriend wear a medical alert tag?
