Why did he do that?

I feel highly disrespected right now. I just told homeboy I’m pregnant over the phone he said “Aw shit” before I could finish everything I was saying about pregnancy test and then when I told him it showed up with 2 lines there was a silent pause for like 25 seconds and again he said “awe shit” and I said am I on my own? He said no I’m not gonna do that especially and I know that’s my child I said okay. I told him today again that the doctors confirmed I’m pregnant he hasn’t responded at all. What the fuck…

I mean he has a kid already who’s 2 so like does it sound like he’s scared or doesn’t know wtf he’s gonna do or just doesn’t gaf? I’m trying to ask here first before I overreact off my emotions
