Your opponent is on offensive so do not expect DIVORCE to be easy.
Once initial shock of various actions against you is diminished , you must prepare your defense to exhaust the opponent.
Time is biggest leveler.Memory of witnesses will fade, interest of opponent will also fizzle so it will be sure, simple to come out of your present turmoil. That is what happens in many cases.
If you feel after divorce you can get any other to bat with you, it will be nightmare or you will have to make many many compromises.
You opponent is aware of your dilemma and also can not resettle so terms of DIVORCE or MCD will be most demanding.
If you can come in terms with these hard facts staring at you than only there will be light at the end of tunnel.
