Which constellation likes to talk about ex least?

I think it is Aquarius, because my boyfriend is Aquarius. Every time I mentioned his ex-girlfriend, he got angry and then ignored me for days.

I remember once before, he always joked with me that I was ugly, with small eyes and a beautiful mouth, and I couldn't make up. I asked, "Then your ex-girlfriend is good-looking, with big eyes and a beautiful mouth." Then he got angry and ignored me for several days. Later, I took the initiative to admit my mistake and said, "I will never mention his ex-girlfriend again." There may be many constellations that don't like to talk about their predecessors, but the most serious one I have ever seen is Aquarius. Maybe he suffered more injuries before and didn't want to bring his sad mood to a new emotional world.

No matter which constellation, since you choose to be with him, don't uncover his scars. You should trust him enough. Even if you want to talk about your predecessor, you should grasp the appropriate occasion.
