Is this toxic or normal?

I wonder what people might think about my relationship.

Me and my boyfriend have been together for three years. Living together for about a year and a half.

We broke up once and moved apart. Because of an addiction on his part that I couldn’t handle anymore and it led me to text another guy. It never went past a couple texts. When we were broken up I did sleep with someone else (he knows about it now) and I regret it with everything in me.

After five months of breaking up he told me things were going to change. We have really put in a lot of effort in being together and working through our problems. We live together again, we work on communication every day, we talk everyday about how we both feel (I have a lot of hurt feelings towards his actions during his addiction) he has completely stopped from what I have seen. We still argue because we are both poor at communicating but one of us will usually say we need a break and come back together after a few minutes and explain more calmly and then we are able to solve our issue.

I see him trying and I’m stepping up too. Does this still sound toxic? Or is this just normal ups and downs and us realizing we love each other and want to really try?
