Has anyone been cheated on during their pregnancy?

Just curious to know if anyone else has been cheated on during their pregnancy & forgave their partners and took them back. If so, has your partner changed and how is your relationship now after he hurt you?. I took my partner back after he cheated but the trust is gone and it feels different. I’m still hurting but I believe he’s changed but my mind set has changed towards him. But I want things to work out because of our baby.
