I need some advice

My Ex- Boyfriend got angry and grabbed me one morning pretty hard and held me against the wall by my neck he didn't choke me but Ive never been abused or held in that way this happened for the first time Feb. 18 I called the police and they took out a felony and misdemeanor warrant for his arrest I was 4 months pregnant at the time with me and his first baby right before he grabbed I happened to look in his eyes an he looked so dark and emotionless.... they didn't arrested him until march 29 and I went to a hearing for his bond on April 19 I am now 6 months pregnant looking at him again for the first time brought so many fears and negative thoughts and I started to feel like maybe I shouldn't have called the police I mean he didn't choke me I felt Like I made the wrong choice maybe I overreacted that I could've just put him out since we lived in to different cities he wouldn't be able to come to me and I found out im having a boy any everyone always say children especially boys need their daddies but now I have to choose between letting him see his daddy in jail or not?

I don't want him to have a long sentence just 1 or 2 years for him to understand its never ok to put your hands on a female and to understand he put himself in this situation. So he can teach his son the same

I just hate he gonna miss the birth of our son he was suppose to be there ugh
