He betrayed me again

He’s betrayed me and hurt me again & again. I’m so stupid to keep believing him and going back to him. 10 years and we have a daughter. I caught him again on Father’s Day cheating. I don’t even know how to respond. A long paragraph is pointless. I need support right now ladies. How do I stay strong for my little girl? I don’t want her to see mom go through this cycle over and over. I don’t want her to see me cry or yell and fight anymore. Help! 💔💔💔💔💔 this was really all he said to me. At this point I feel like I’m just disrespecting myself! My mom says to go live with her but I don’t know. She took care of her mentally sick sister for two years and she just now has her house and time with her husband back. I don’t want to intrude.
