Need Opinions

So my sons father ask his ex girlfriend if she wanted to meet our son (I never met the girl, had to find out who she was from his sister in law) I don’t know if it ever happened he says no, but I don’t know if I believe him. Along with asking if she wanted to meet him he was even willing to take our son to where she was to do so. He also text her every morning telling her to have a good day or ask how her night was ( there was even a time where he text her and I in the same minute and said the same thing) anyway, things have been going well we split custody of him, but I didn’t grow up in a “broken” home and neither did his dad, so it kinda like I don’t want him to. But I’m scared, do I trust him again and try to work things out? or just continue to do things the way they are?
