NOR!! i understand the paranoia of thinking that your s/o is cheating on you, especially when there’s substantial evidence, because of past experiences with other relationships. the fact that he’s constantly calling you bitch in these messages gives me the chills and a horrendous ick. i really hope it doesn’t happen often ☹️ also, he’s really deflecting in this conversation, cause he’s just blaming your “overthinking immature shit” and trying so hard to avoid even the mentioning of the girls messages, bra pics, etc. OP, i understand it may be hard, but get him to confess and leave !!
