Recommending therapy wasn't a FU. A lot of millenials, especially older millenials, still feel like getting therapy or seeing a psychiatrist means you're "crazy" or having it recommended means you think they're "crazy." It's not the case, but that's a perception some people still have, even if it's outdated.

It does sound like she needs therapy, and she probably should have had it before getting with someone who it sounds like may be a manipulative scumbag. Unfortunately, with those unresolved issues, she may be clinging to this manufactured "happiness" and throwing friendships out the window. I wouldn't be surprised if you hear from her years down the road about how big of a mistake that was and she wants to reconcile.
