Husband attending therapy with ex wife??

Melissa

My husband's ex wants them to attend co parent counseling together. I'm a little uneasy about my husband spending an hour a week in therapy with his ex wife. I can understand how it could be good for the kids... But honestly I didn't think they had a problem. She has made comments to me in the past about wondering why their relationship failed and what went wrong... Makes me feel like she's looking for marriage counseling not coparent.

ANYWAY my question is, is this something me and her husband should be involved in or just the biological parents?

Background: they've been divorced 5yr. Me and step dad both entered in the kids lives right after divorce. We have 50-50 custody
