He says you're useless, lazy, and don't contribute anything?
Yes, he's emotionally abusive. Without a doubt.
Here's the thing, OP.
Emotionally abusive partners are NOT abusive 24/7. If they were, they would never be in relationships in the first place.
Emotionally abusive people can be absolutely wonderful at times. And it's not always fake. They can be generous, fun, playful, attentive, romantic. It's how they are when they're NOT being this way that is the problem.
The way I differentiate is this -
How does this person act when they have a problem with you?
A healthy, loving partner might get annoyed, but won't call you names or say anything outrageous or scream in your face.
A healthy loving partner basically won't call YOU anything. They will talk about how something is affecting them.
For instance, they might say:
"Let's talk about the division of labour in this household :p" with a cheeky grin, if they are the playful type.
or
"I feel overwhelmed with how much I'm doing, and I don't know if I'm seeing things clearly, so can we talk about it please?"
They WON'T say things like:
"You're so" "You always" "You never"
Just because you are having a baby with this person, doesn't mean you need to be in a romantic relationship with them. It's far better to teach your child what healthy boundaries look like than to stay with an abusive person, as this will only teach your child that abuse is ok. They will then repeat the same patterns in adulthood and be very likely to end up with an abusive partner themselves.
I recommend having a look at DoctorRamani on YouTube and see if you can relate to any of the things she talks about. She focuses on narcissism, but a lot of what she says describes emotional abuse.
Good luck OP.
