Is there any way to record a conversation about this? Maybe getting him to talk about the letter and even having it recorded that he is threatening you with it.
If you could consult with an attorney without his knowledge maybe you could get some idea as to where you stand. Yours sounds like a good case for Divorce from Bed & Board.
“What is divorce from bed and board?
Divorce from bed and board is a fault-based action, usually brought by an injured spouse to get the court to order the other spouse out of the residence. If brought in conjunction with other claims (custody, child support, distribution of property), a judicially ordered separation pursuant to the prayer for divorce from bed and board establishes the separation required for those other actions. The complaint for divorce from bed and board must be verified and it must contain the required allegations of residency.”
“What fault grounds can be used to file for divorce from bed and board?
The complainant seeking a divorce from bed and board must establish at least one of the six fault grounds enumerated in the statute: abandonment, malicious turning out of doors, cruel or barbarous treatment, indignities, excessive use of alcohol or drugs rendering the condition of the other spouse intolerable, or adultery. Further, the complainant must allege that he or she did not provoke the other spouse’s misconduct. The right to jury trial in an action for divorce from bed and board is governed by the statutory provision permitting a jury to make the factual findings on issues of fault.”
The allegations of abuse would have to be proven before you would lose your child. If you are being emotionally or physically abused there is another section that you need to look into. I do not know what it takes to prove rape by a spouse but I believe that they can.
