Depression

My ex cheated on me. And we have a daughter together. He didn’t talk to me for 11 days on the 12 day he said “respectfully I don’t want to see u anymore or have any sort of interactions with you for awhile” so through my mom I would like to see my daughter so do not deny my daughter from me, we have to discuss how we going to move forward with our daughter because I still plan on supporting my daughter financially and continuing my relationship with her” It breaks me because he didn’t say sorry for cheating or tried to make this family work. I feel like I betrayed my daughter out of a family.
