I can say this about Aries. They love conflict hence war. I would take some of his queues a little cautiously. For example, when he wanted you to e-mail you him instead of talk about it. This is clue number one. I feel like he is not willing to confront the issue. It is rather easy for him to read a letter instead of deal with your feelings face to face. However, I think straight up honesty is the best policy.
I personally dated an Aries and it was nothing but an emotional rollar coaster ride. For some reason Aries are attracted to Libra. I personally think it is a quest to rival up a peaceful person.
