Cheating tagged addicted husband

My husband of 4 years together for 9 has had a very bad habit of constantly going on Tagged talking to other women and sending nude pictures . Talking about sexual things and etc. I forgave him for this a few times in the past and yet again he has the same excuse that he won’t do it again and to trust him. Sadly I can’t because I’m the type of person where when I see disloyalty/sneakiness especially from my man and another woman, I get turned off and I don’t want to deal with you anymore. So he calls me bogus and that tagged is like Facebook and any other social media app !?!? Hell no! The things I’ve seen on his page and the women he was talking to sounds like quick hook ups for freaks on the low. I do love him and don’t want him to be in love with anyone else because of our kids and our “good” moments we shared but at this point I know it’s gonna be hard as hell but I have to let him go 😢 I just don’t know how to get over someone who has hurt me so bad but also loved me in so many ways over the past 9 years😢😢😢😢😢
