Jadiry, focus on what you need to do.
1) Divorce, he want to file for divorce, based on
what grounds? Sue himself for adultery? If there is no valid
reason, will have to go for separation, 3 years. Be careful if he
wants to back date the date of separation, that is a false
declaration and it might come back to haunt you. If he wants to sue
you for unreasonable behavior, not performing the duties of a
spouse, are you willing to accept? It all depends on "yi kou qi"
and whether you want to get out of the marriage fast and also
financial. If he want to sue you for divorce and you chose not to
contest, you don't have to fork out any legal fees. But I'm afraid
that you might lose out when it comes to division of matrimonial
assets of you don't have a lawyer to advise you.
2) Plan for your life after divorce. Hopefully your
finances and job is secure, then you only need to worry about
shelter.
3) Spend time on imrpoving yourself and meeting more people.
Don't dwell on your own problems. A lot of time people will start
to question about their own self worth, whether it
is their own fault. Let me tell you this, sometimes there
is no explanation other than the fact that the selected partner is
an ass, and you failed to see it earlier. And the way to treat them
is like the way you would treat a cancerous or gangerous
limb, cut it out as soon as possbile. Spend time going out
with your friends, knowing more people, working out, revamp your
wardrobe etc. Build up your own self esteem, live a happier life
without him.
From what you've described, you have a terrible husband. One
day, when you finally settled your emotions, you might even be
thankful that that stupid woman took the burden off your arms. Good
luck.
