<human>: Can you give me a shortened version of the text?

Background info: Husband recently had somewhat of an emotional affair (was calling someone else non stop, hiding it, all that). We are trying to work through that. 

Yesterday I couldn't help myself (even though I know this is an invasion of privacy, wrong etc -please spare me the comments about this being wrong I already know) and looked through his phone while he was in the shower. 

He had a convo with his friend, involving his best friend sending him home videos and sent him a pic of some girl naked, talking about how good she is and how she has skills. 

Husband writes back questions like 'rate her 0 to 10', and such. Then the friend writes something along the lines of "yeah your wife is a lemon". And he writes back "haha" and then said what you got and his friend writes 'freedom'. 

This is not the first time this guy has disrespected me, he was running back to my husband's ex and telling her all our personal stuff that my husband told him, he has insulted me openly before, and he basically treats me like shit. 

I wrote him saying 'thanks for sending my husband pics of your bitches'. and he wrote back 'You're insecure and controlling, blah blah" (a long paragraph basically just being obnoxious). Keep in mind the guy literally does not know me - he lives in another country and I've met him once.
<bot>: Okay Reddit: Should I feel as shitty as I feel right now, or am I overreacting to 'guy banter'. I am so lost at this point.
