Anyone?

Has anyone experienced this? I’ve been in a relationship with my boyfriend for around 10 years. It started off great. Eventually drugs/alcohol came into play and he become mentally abusive, the way he spoke to me. Sometimes it was on the verge of being physical but never hit me. He is now sober, has around 2 years sober. He seems more clear minded and stable. And it’s been a lot better. None of the mental abuse or physical. Are some men only abusive during their state of addiction? If they are sober it’s completely different? I can’t help but to have it in the back of mind, sort of paranoid like the abuse will start again even being sober.
