Husband is addicted to dating apps

My husband has been caught on a dating app before in the past and I have a accepted it! He just recently was on there again and was even texting a female on his phone right after we had sex and deleted it! I know I’m stupid I know because since I allowed it before and accepted it he will just keep doing it until he gets caught then it’s I’m sorry I deleted the app I changed my number let’s be in love again???? What’s crazy is he still wants to have sex with me after I seen the bull crap he was on last week! We have since then been separated but he constantly contacts me sounding all sad and how he won’t do it again and he just wants me blah blah blah! Ladies I think I am finally at that point where I am done! Yes it took me a few dumb spells and naive moments to realize that I am worth more then that! We have two kids together and I’m not gonna lie it’s hard!!! 9 years gone!!! But I can’t force someone to love me how I deserve to be loved and be faithful!! I don’t judge anyone but after someone cheats on you and talks to other women( because cheating is beyond just physical ) it pushes you away and you never feel the same anymore ! I refuse to give in and believe him “again” I have my babies to think about! Mentally and emotionally I’m very torn up so I’m in the process of seeking a therapist to help cope with a lot of things. Pray for me as I go through this divorce as it is very very hard 😓
