Dealing with MLC is a lot different than a WAS spouse. Just compare Puppy Dog Tails advice to Jacks...both have been here for awhile and yet their approaches are totally different as are their situations.
The jealousy thing will jump up...the key is Gal'ing. Once you start Gal'ing effectively the jealousy will get less....because you will have your own fun things to do. Be they movies, reading, working out, or joining the guys for a game of flag football...they will be fun things for you.
