from your post it may be that your wife is suffering some kind of behavioural disorder.
Seems very hard to understand how she could 'fall in love' with someone who barely spoke to her and wanted little to do with her, all in ONE day!
Of course she would be vunerable for any predator and has had at least 3 affairs, dont be too unprepared to learn it may have been more if this is indeed the case.
Ok you've filed for Dv BUT what do you want?
I assume you are asking for help because you DONT want to really divorce is that right?
Well I'd have to say until she addresses what her issues are which seems to allow her to do this you will probably find it very difficult to win her back.
But you have to start somewhere so first of all read the info on this site then look at getting his needs her needs by Harley & Surviving an Affair, by Drs. Harley and Chalmers.
This will help you understand the affair process & common dynamics.
If you can slow the Dv up you may wish to do this to give you some time to work on the marriage using the MB principles.
With multiple affairs it would appear there are some deep seated issues that require to be resolved first.
I therefore suggest you contact Steve harley here on this site to discuss the issues in your M in depth and work on some solid plan to fight for it.
Maybe you have been a conflict avoider and your WW feels she can do what she likes, could be many things so get some EXPERT advice.
You can arrange that by clicking on the following link
Counseling Center I feel its beyond non expert advice right now.
However once a plan is in place you can vent here, discuss, talk, whateveer as the need srises.
