Malti, I am not sure if you are looking for any type of suggestion here or just needed a channel to vent out your anger. Either way, I think since this is your marital status as of now, you should think of moving on.
as he is talking of divorce, you too should consult a divorce lawyer. you should definitely ask for a good amount in alimony and child support. as the father, he also has some responsibility towards your child, so don't let him forget that.
