OP I'm so sorry
Pleae please listen to me- I have had a very similar upbringing to you and spent years of my life with this kind of man until I got help. I do understand so please please listen to the advice on here.
You are in an abusive marriage.
You need to recognise that now. You are co-dependent due to your upbringing and you were never taught healthy boundaries, hence tolerating shite behaviour from your husband. Not your fault, but it IS your responsibility as an adult to overcome this. Your husband was also probably attracted to you because he sniffed you out as a victim he could bully, control and treat like shit.
Take a step back and imagine a friend of yours told you this was happening to her:
Husband shared deeply personal medical details with a virtual stranger- bowel disease, internal examination, pains WTF?!!
Husband financially abusive
Husband controlling over phone use
Husband minimises feelings and gaslights
If you raise your child in this environment they will grow up deeply unhealthy without healthy boundaries of their own and they will go on to become only one of two things: a victim of abuse, or an abuser. It's not your fault you were never taught how to be boundaries and look after yourself. BUT It is now your responsibility to change your life to stop this from ever happening and to give you child a chance at a secure healthy upbringing.
You must take steps now OP:
- Tell the midwife and ask for support to kick him out. This is SO important.
- Also tell your two close friends to get moral support
- Tell him to leave and move to his family
- Change the locks on your property
- Do NOT disclose anything to his family nor trust them again. They don't have your best interests at heart.
- Rely on your two good friends for emotional support
- Seek further support from outside agencies such as midwife, Women's Aid etc
- Access the freedom programme online
- Educate yourself on co-dependency. Try Lisa A Romano on YouTube as a starting point.
10. Ask your GP for a therapy referral, or access low cost or free local therapy, and have therapy throughout the rest of your pregnancy to support you to develop healthy boundaries, healthy self-esteem and be a healthy parent.
As much as you will love your child to bits, you need to recognise that (through no fault of your own) you are not fully equipped emotionally to parent your child in a way that will change the patterns established. As it stands your child will end up without healthy boundaries or self-esteem as an adult either. Even worse if you were to stay in this marriage. Just think what that child would witness - they would learn that this abuse is what a normal relationship looks like. You need to remove yourself and your child from this toxic environment / marriage now, and you need to seek therapy to learn to break those patterns of behaviour. You can do it
