CheAting?

Been married 3 years after dAting 5 years

We are both 25 and juz had our first baby last month. Last night i found txt from an ex-coworker of them flirting. Didn’t have much really but a kiss “muah” from eachother and an “ok love”. Now this is the second time in 3 years that he has talked to another women online/txt. He cheated on me at the very beginning of our relationship and i forgave him. Would it be too pathetic to divorce him over txt messages when i have already forgave so much? I am done with his games. The only reason I haven’t left him is for my child. He deserves to have a family. Husband is begging and promising a real change this time. I have been emotion less with him since i found out. I am numb and I don’t cry , I don’t scream. I feel sorry for him at this point. Seeing the state of despair he is in makes me feel sorry for him because he seems so pathetic. He put himself in this situation once again. And i had a feeling he was up to something, every big moment in our lives he has fucked up by doing this stuff. Idk if i am juz being stupid for letting him try and repair the damage.

Update:

I agreed to give him 1 more chance to show change. This its all him. I will not make excuses for his behavior to keep me happy with him. He has 1 year or less to show me. If i am not happy then i will take my child and go. This i am only doing to give my baby the possibility of a normal family. Its gonna be pretty sad and definitely hard because all trust is out the window. I promise myself that if its all about arguing and nothing healthy is happening i will leave before that year is up. He is pretty much starting from zero with me because love is not in the picture right now. I will stay in my home do my wife chores, but he has to woo me again. Spyware will be added to his phone,with his knowledge, all social media will be deleted , he is walking on a thin line. I am also giving him this last chance because on the messages i read it was obvious that he was trying to avoid the flirting back and was strictly talking about work but his idiot ass ended up giving in. Out of the whole message i read only two things stood out ,the muah and the ok love. That dirty slut asked him for his picture and he denied it to her saying he didnt have one when i kno for a fact that he has plenty of pictures of himself. She herself is married . She is a home wrecker and is well practiced from my research. Its only been a day and she has since quit her job which wasn’t with my husband anymore. She is now hiding from me. I do feel stupid giving him this chance but i wanna kno that I tried my very best to keep us together so if it doesn’t work out at the end i have absolutely no regrets getting on with my lofe without him.
