I am not sure I understand the OP, capponz.
Since Kostya is also unsure, let me offer my guess in case it is relevant.
It looks like he/she wants to be able to see all messages of the conversation in the list view, but in the message view (with the message switching using swipe enabled), exclude his/her own messages ("sent") from viewing/reading.
Again, I am not 100% sure it is correct, and in the beginning I was surprised why one would need that, but I guess he/she knows what he/she wrote and doesn't want to read that.
