Having helped my Father through Moms passing at a young age, I completely agree with the sentiments that have come full circle that an online forum isn't really a place to plan your spouses support network when you're dead. There's a whole world of estate management and planning . Helping someone that shows up and says "my husband was (insert username) and I could use help with (insert items)" will probably solicit responses but they are still worth exactly what she pays for them. After all, it's a public forum.
Estate planning: If you don't do it while you're here, someone else will have to when you're gone. Get your will and trusts in order. If you're mature enough to make a child and/or marry, then you're mature enough to put together an estate plan; which should be crafted as a living document so long as you are a living body. There are plenty of boilerplate documents that can get you started. Consult an Attorney if you do not want them to turn into a point of contention between grieving family members. A cut and dry estate plan mostly mostly takes care of itself once you're gone and removes a huge burden off the families shoulders.
My Wife and I were discussing this just this last night due to an acquaintance that passed. We are both relatively young but we know where we stand on many outcomes. One of the biggest things that never gets discussed is advanced directives. Do you wan't be resuscitated repeatedly after brain damage? How about if one of you is starts developing alzheimers? Is their a set of circumstances you feel would change this? We actually had a somber discussion about cancer treatment outlooks advanced directives and realized we needed to update our estate plans. I don't like discussing this stuff one bit but it's got to happen before because laying the burden on someone else is a very unfair thing to do.
Currently I have trusts in place and durable power of attorney setup since I work in a field that happens to come with slightly higher risk than most but even with that risk, more danger statistically exists on the freeway drive than most people deal when they're actually on the job. Things like getting plowed on the highway do not discriminate against age, gender, creed, etc. Vehicles are assembled with hundreds of bolts. It only takes one nut behind the wheel to scatter them in every direction.
Maybe you have tomorrow, maybe you don't. Regardless of how you go, you're not going to make it off this Earth alive.
