New Marriage - To form an LLC in addition to existing LLC/S Corp?

[Eric Barnett]

When I refer to a new partner I mean a future spouse (fiance) who I will be investing with. My goal is to be able to deduct business meals, travel, etc. that we already commonly do. I currently work in energy consulting and have my single owner LLC that is classified as an S Corp. I'm deciding whether or not I NEED to form a new LLC with both her and my name associated with it in order to start our real estate investing career and be able to take the tax deductions.

Am I able to deduct the business meetings, travel, etc. under my LLC since if it were just me I could simply run my properties through this without having the hassle of another LLC and additional tax return/bookkeeping.

Any insight from those of who have been in this similar situation whether it be H&W or simply new to real estate and looking to decrease tax liability.  

Thanks for the advice!
