Keppra Side Effects: Angry BF

So my BF start taking the Generic Keppra in May 2018 after his 2nd episode of seizures. Before then, he's always kind of had anger issues...but nothing just THAT bad. Recently, lets say since last month I guess. Maybe a few months ago...I'm noticing he's a LOT more snappy,aggressive tones, SUPER easily irritated, somewhat disrespectful with his tone and the way he talks to me sometimes...He talks to me like I'm his homeboy instead of his woman....& when I address it, he has no understanding & downplays it as me being too sensitive or says he's not even "mad" or talking to me crazy. He's always had a tendency of blowing up a problem and making it bigger than what it is but now it's just getting ridiculous & exhausting. I talked to his dad (who's been staying with us for about a month now), and he's even admitted that it's not just me...he's even snappy with him and always arguing with his mother. About the smallest things. He just appears to be a mad man sometimes. I was thinking maybe he's just tired of me so every little thing I do annoys him but after talking to his father, we came to the conclusion that we think his meds are finally having one of those side effects (mood swings, aggression, etc) with a combination of some things he watches on YouTube...stress also...but definitely the medication. I'm scared to ask for a change in the medication bc it seems as if it's working (I guess or his condition just isn't as critical you know?) because he's been seizure free for 6 months. (He's only had 2 episodes his whole life, he's 28, 5 seziures total) Then, I'm scared maybe changing meds may trigger a seizure bc maybe the other meds they have available may not work as well. Neither of us is a fan of medications to start anyway but we had no choice here. I say all that to say...I'm here on this forum as a last resort to get advice and support. (I've even made an appt with a counselor FOR ME, this week to seek more help). I've thrown out there plenty of times that his anger is a concern..& he should see someone about it but of course he doesn't think his problem is that serious. But it is. We have a soon to be 1 yr old together & I want nothing more but to keep my family together. However, I refuse to deal with disrespect and his anger issues for the rest of my life. It's just draining and he's just not the same anymore in some instances. Because I know these meds could be causing it, I'm not trying to give up on him just yet. I want to do everything I can to help and be patient. I plan to ask him to read this book with me on relationships as another help tactic for our relationship. We'll see how that goes. I'm also going to try scheduling us some yoga/meditation classes (he's open to that) (I told yall I'm trying EVERYTHING) But at this point I'm just drained and I don't know what else to do! If anyone else is experiencing this with their significant other or YOU ARE "my bf" and dealing with the side effects...or have experienced this & have come up with a solution, please share!! I'm open to all suggestions..advice...resources I can use to help my situation..anything! Thanks!
