The point isn't that she is excused from those threats because of the anxiety, the point is that she may be less rational than usual (and women are always less rational than men already) because of hormonal interference.

OP wants to solve that problem. Telling him that his wife is his enemy, or that he just needs to rule her with an iron fist, is not going to solve that problem.

Never once in the history of CI have any of the marriage counsellors on here been able to produce a single real-life example where these kinds of problems have been solved with that kind of approach. These aren't questions of doctrine or theology. Your wife isn't someone on the Internet you're in a debate with.

Who here said he should call her his enemy or rule with an iron fist?? what? Stop projecting.

From what I'm seeing, the problem is not going to go away. She will keep doing what she is doing. If the husband doesn't want her to do something like what she is doing, and its reasonable (which this scenario, him asking her to stop it is) she needs to listen to him. You can't reason with this stupidity. It's either that or he gets walked on.

When my wife has anxiety about something or is upset, we definitely talk about it. If my wife started throwing apple cores around the room because it's "healthy", she is going to stop it because I said so. This kinda proves women are adult children. Men don't get away with this BS.

This woman already doesn't respect her husband's authority.

Well, since so many posts are anonymous in here, I don't actually know who said what most of the time. But the constant rhetoric of "she's manipulating you", "she's not a traditional Catholic", and so forth encourages a hostile and combative approach to the problem-- which is the approach one uses with enemies.

I wonder why she does not respect him. Or didn't to begin with. Or... decided to marry at all.

Doesn't excuse what she's doing in the scenario OP gave.

Don't get me wrong, finding help for it is a very good idea. I personally think OCD is heavy personality trait, not a "disorder". If anything it's more of a spiritual thing.

You telling me leaving her husband will not worsen her anxiety/OCD? I think it would.

I am surprised at some of the comments here insinuating how he should have chose better or alluding to her changing from when they were engaged to when they were married.

4 weeks post partum is perhaps the absolute worst time to be thinking about how a wife has changed or shown her true colors. I’m so glad my husband didn’t think that way with me. He doubled down and loved me even though it was hard. His steadiness and firm but gentle principles made me respect him more (each time after I got through post partum 6 times 😆). I can say for certain I respect him more every year we are married because of his wisdom and patience with me when I am unhinged and irrational 4 weeks postpartum.


There will be times your wife doesn’t respect you, even if she’s trad. You still have to love her and be patient. There’s times that husbands will not love their wives well. We still have to respect our husbands. We honor our promises to God and depend on the sacrament to get us through. This is how we get to heaven with our spouses. We sure don’t go into marriage perfect! We help each other.

It’s hard to say, we have such limited information. But as OP responds I tend to think getting through post partum then getting some help with OCD will go a really long way.
I think you are doing well, OP!
