<human>: Can you provide a brief overview of the text?

Long story short, boyfriend of four years (that has sexually, verbally and otherwise abused me) claims he "didn't know" messaging other girls on here telling them they look like goddesses and have perfect asses, talking to them in great detail about my mother (including disgusting fantasies that i got to read, hoo fucking ray) and calling them my pet name would "hurt me as bad as it seemed to". He's done this before, too. Also actually physically cheating at least once that I know of, and probably again recently since he's acting so freaking weird around one of our friends or any time someone mentions her. Like he'll go out of his way to "hate" her soo much around me. 

Ugh. 

I'm an almost-emotionally-fried ball of sad right now.
<bot>: confronted bf about reddit messages to other girls (he's a repeat offender!), he said he didn't know it would hurt me and expected me to shrug it off.
