Ok, whether it was 3, 5, or 10 messages or conversations out of thousands, you cannot discern the entire context of the relationship from that little bitty glimpse.
Yes, you may be able to say that on these occasions there were problems in the relationship. But that's all you can say. The "content" of these particular messages is not particularly revealing - it's not like a man telling his wife she's going to pay for talking back to him; it's not like a man telling his girlfriend that she better not look at John that way again or she'll be sorry; it's not like he said, I'm sorry I choked you ..but I just got out of control and that's not really me, I promise it won't happen again, please dont leave.
You see what I'm saying? If you see messages like that you might be able to conclude from just one message that this is an abusive relationship. That is not what we have here at all.
From what you have said there, it seems that you do not have a very in depth knowledge or understanding of how these types of relationships work .. particularly the bits I have put in bold.
