Advice

I started dating this guy when I was 3 months pregnant and I've known him since I was 14 and we've dated before but broke up when I was 16 I'm 19 now and 9 months pregnant and he keeps ignoring me and being distant and he has only seen me once since I got pregnant ( he lives a town over) he says it's cause it hurts him to see me pregnant by another guy but it's not like I cheated on him and he always brings up my past I just don't know what to do anymore
