Pregnancy hormones?

Long story but please keep reading

So I dated my husband for 2 years before we got married but it was a long distance relationship most of the time because he’s in the army. I have a son from a previous toxic relationship and the sperm donor is not in the picture. After months of dating I told him I really want him to get a long with son because that’s very important to me and he agreed and was always nice to him but now that we are married I feel like they don’t have a connection or good relationship. I always tell him that it would mean a lot to me if we go to family concealing so he can learn more on how to handle situations when my son is misbehaving because hitting him all the time is not the solution. I know my son can be a little too much but I don’t like the way he handle the situations and he just never listens to me and doesn’t want to go family counseling either. Now I’m 4+2 days pregnant and I feel like a horrible person for thinking about abortion because if my husband doesn’t get along with my kid and doesn’t even care to make things better how can I have this child in a home where there’s no love? Also today I wasn’t feeling good so I told my husband I was gonna take a nap to please watch over my son and he agreed but then when I wake up my son tells me he’s hungry so when I go to the kitchen there’s was a piece of those frozen breakfast sandwich that you put in the microwave and I got upset because that’s not something a kid should eat for dinner. So my husband made him chicken nuggets with pepperoni???? I got more upset because I told my husband that’s not a healthy dinner for a child so he got upset and started yelling and calling me retarded. Like I don’t know what to do or think please someone give me advice am I exaggerating?
