Help me? Feeling so low!!!

[user1489269570]

So I've been in a relationship for 2 years and abit. I've had a kid with him (10months) And found out I am pregnant with another. The thing is we have been having a rough time. I have not been perfect. And neither has he, I refused him to come in my home since he left. And I would put all his stuff in between 2 doors but he wasn't having any of it. I decided to call the police to see if they think it is the right thing. And then she started asking about abuse and I said I have had a few bruises from him from him grabbing my arms to stop me from hugging him.And I said my family thinks it's emotional abuse. He has called me weak. Now I've got an officer coming around later to see if I'm ok. I can't stop sobbing, I feel ill, this is meant to be a happy time, I want him back!!!! It's a mistake. I messed up. Would the police involve social if I got back with him? Or would the social take my kids away if I do? Or does anyone think they have involved social? She never said she was doing to so I thought they have to tell u first? My kids do adore him, especially the twins who doesn't have their father in their lives. He took them on like his own.
I have 3 other kids and 1 of his kids and another one on the way. I mean I would never put my kids in danger for a split second, he has never raised his hand at me. He was in a relationship for 10 years and never hit her either. And I know this because I have bumped into his ex in town and has told me her side and said nothing about hitting. Advice please!!! Thanks
