ok I've literally been in this exact situation lol. dated another aries for almost two years

the "powder keg" thing is real BUT it's not the whole story. yeah we fought... but we also made up fast? neither of us holds grudges bc we're both already onto the next thing

what I learned is that two aries actually have to be really intentional about taking turns. like in a normal relationship one person is naturally more patient or passive. with two aries you BOTH want to lead, BOTH want to talk first, BOTH have the idea that's more important lol

once we figured out how to actually take turns and genuinely listen instead of just waiting to speak again, things got so much better. it's like a skill you build together

so no, not a terrible idea at all. just requires more self-awareness than average
