Married life as a FAST Co. Marine?

I am currently in MCSFTCO in Chesapeake, VA and just found out im being placed in a FAST company. i originally had a prp contract but was told my recruiter did not finish my security clearance so i am not able to fulfill my contract. I am married and have heard being a FAST company marine is very tough on married life due to the amount of time being gone. If anyone has any knowledge of help on the situation id appreciate your help.
