She's not still in your bed, is she?

I don't know if I would call that a sin, but that doesn't seem right.

To answer your actual question, the Bible mentions lust and sin a few times. "If you look upon a woman with lust" is one, which I don't think qualifies.

And then the story about remarriage with the seven brothers - when Jesus says marriage is not what we imagine it to be in heaven (after death) so if you still feel for your wife, there is nothing that would seem to be wrong about it.

One question I would ask is "What would your wife tell you to do?" and take that answer to heart.

The fact that you are even concerned about that, in these dark hours, tells me clearly The Lord has great regard for you.

Do not give in to sin; resist the temptation to act on the impulse, and I’m pretty sure you’ll light up like a beacon of hope for others around you.

I’m not a priest, so I can’t say this with authority, but I can suggest that resisting even the thoughts of lust will probably shine light on all sorts of areas in your life, opening many doors for you, lighting your path, healing your soul.

The Lord knows what you’re going through, and He gives this cross to people whom He knows will have the capacity to shine through it, for Light to the world.

I don't know if you're asking hypothetically or not, so I'm going to write my post as if you're legitimately affected at the moment.

Not a sin, you were married to her, you were as one-- as it's supposed to be-- she isnt a stranger or someone else's or otherwise--- she was your wife. It is extremely common to desire physical intimacy with a recently deceased spouse. They were a big part of your life after-all, which is part of why you married them in the first place. It will lessen over time, just like all things do. IMO, simply recognize the desire felt for your passed wife as positive note/reminder of your time together and your connection to her. Give your mind time to work through processing the big change in your life. Losing a spouse is extremely difficult, do not make it harder by mentally punishing yourself because you still desire the connection you had. Just give it time.

Obviously you shouldn't build a golden fap shrine to your passed wife, because that's not going to put you in a healthy psychological/spiritual position, but don't beat yourself up over having the thoughts/feelings from time-to-time.

IMO, whenever you actually feel like you want the intimacy of another person again (and are ready for it), I'd recommend dating other widows/widowers, because all the complex feelings of 'im still/was married' or 'how im dealing with this change' are better/completely understood by both people and it'll be a common ground you share where you don't have to feel guilty over all of your feelings as you sort through them.

You were married, until death did you part. You fulfilled the vows you gave to her and to God. I do not see any fault here. If you do eventually decide to be with another person again, just make sure you show them the same love/devotion that you showed your wife.

Life is hard and it doesn't ever get any easier, we all just have to march through the mud of it one step at a time. Goodluck o/

No. That's how new children are made. You are all good. No worries.

Wives used to die all the time. Childbirth.

No.
