Hi Mira835,
Regarding recommending a solicitor, I regret that I am not able to help you with that, and you would have to ask around your friends, colleagues or other forum members.
On the other hand, do take care not to allow yourself to get hurt. I understand from you that you are still staying under the same roof as the other party. if need be, do apply for a Personal Protection Order ("PPO") for yourself. However, verbal threats along are generally not enough.
Do you mind if one asks how long have you been married for? are either party Singaporean? I would assume so because you have a HDB flat together. Citizenship determine whether the Singapore Courts have jurisdiction to dissolve your marriage and the length of marriage determines the proportion of division. For shorter marriages, the Court would look at the proportion of direct financial contributions whereas for the Courts are more willing to consider indirect financial contributions to the family for longer marriages. In this regard, there is no starting point for division though.
Take care of yourself and be happy
