This mf.....

So I'm pissed and ready to stomp a couple nuts...found out my husband has been messaging and entertaining other females on social media flirting and swapping photos and crap. well i brought it to his attention and he swears he's never stepped out on me and that these females don't mean Shit to him. And that he does it cause it feels good to have other women WANT him. Says he would stop but now it has come to my attention that he's been looking up personal ads on sites and resounding to them. I need some advice please before i hurt this mf.....😩😩
