What is the best way to approach this situation?

From a practical standpoint, this should be disclosed in order for her to be able to provide an accurate family medical history if you know the father. That’s the purely practical view.

The emotional standpoint is the tricky part. If you aren’t in counseling, I’d suggest you go get some counseling and use those sessions to work with a therapist to find the best way forward for all of you. It’s going to be painful, but the only way through it is actually through it. There’s no skating around something like this.

This is only how I would react

First I'd be very angry, probably drink and think till I can't anymore.
Being the guy I am, I probably love the child who I thought was mine.
Wouldn't talk to you for days or even longer.

What it would do to me
I'd lose all trust in you, cutting all ties
Probably, think of divorce and leave you and child

The good
I'd still love the child no matter what, even though I'd no longer be in its life.

You
Can be quiet and live a lie which is a tremendous weight and guilt to be carried for the rest of your life.

Forgivness is a blessing not all possess, pray

Sometimes keeping things a secret can be excellent! Good family life, everyone lives w/o knowing.

Unfortunately if the secret gotta come out it is best through you. Am just wondering if u can keep the secret going for long as possible? If it guilt then probably will have to let it out but in a constructive way, which is sitting down with both of them, showing medical proof.

She'll have to know at some point. Why put it off so she herself questions why? It will only make it that much worse.

Instead of one person you'll have two people mad.

I'm assuming that your daughter is young. If not it's already too late.

How old is your daughter,depending on her age that might be a tough converastion,but one that needs to happen.

There is no best way. How are you going to justify breaking the trust and lying to your spouse? He probably isn't going to understand your betrayal. It's more than likely going to end your marriage.

There is no “best time” . You just have to tell him and be ready for things to go pear shaped very quickly.

I would have told him as soon as i knew..

Is there really a need to say anything?
I can't see it accomplishing much apart from making you feel better

Just tell him

If you want to chat you can message me

if the other father isnt in the picture i think itd be best to not say anything. not unless they question you about it.

How old is your daughter?

That poor man and poor baby…

She’s not “Our daughter” she’s your daughter

That won’t be easy
There is no perfect moment!

Dont. take that to your grave

Why did you wait so long? You're already a bad person by cheating on him, but you also waited this long for what?

If you supressed the truth so long, why does it need to be told now?

Your marriage will end. What’s the full story?

If you’ve waited this long, why now ? What outcome are you hoping for ?

Do it during the divorce proceedings

Take this to your grave.

Seppuku? 🤷
