Wow, such language, you scare me, I am just shaking in my boots. 

Well WOW being rude is unnecessary and cussing at a person proves you have to be like 12 years old or just plain ignorant.  Thanks for the help (NOT). 
For your information I did read the manual and all it says is:   

Marriage Post Mortem [Optional - Default: Disabled]
     Prevents the breaking of the marriage lines on the fambly tree.
     Option is experimental and has not been fully tested, so is disabled by
     default at this time. 

Use Awesome Jealousy Code [Optional - Default: Enabled]
     Uses one of AwesomeMod's jealousy routines. Required if you want to use
     any of the optional settings relating to this.

Enable 12 Woohoo [Optional - Default: Disabled] *EXPERIMENTAL*
     Disabled scripted check against 12-woohoo. Doesn't specifically enable
     the action, but can be used with XML tunings that will.

Enable Pedophilia [Optional - Default: Disabled]
     Adult-to-12 actions will be enabled if you turn this on. Be careful,
     though: Pedophilia is wrong and pedophiles go to jail, you sick freaks.

So your precious manual didn't answer my question.  Oh and since your the grammar police your manual is full of grammar and spelling errors, try using the spell check.

Hello I just got Sims 3 for Christmas, I noticed in the game there is a lot more restrictions on marriage then there was with Sims 2.  For example I would like 2 single parents with teenage kids  to be able to meet, fall in love and marry.  Then I would like one of the children (an adult) from one of the parents to marry one of the children (an adult) from the other single parent (neither child are related by blood).  Sims 3 will not allow me to do this.   Would AwesomeMod allow me to do such a thing and what would I turn on or off?

Thank you for your time
Sincerely
