Boyfriend asked me a question did I over react

So I’m pregnant and my boyfriend just asked me did I get pregnant to get back at my sons father for having a baby with someone else but we planned this baby together and had a miscarriage in September needless to say I was absolutely hurt and I started crying am I wrong for over reacting his response is it’s just a question and am I going to drag this out for hours . I just don’t know what to do he consistently asks me these hurtful questions and never sees a problem with it I work 16 hours most days we don’t live together and I’m raising my first son by myself I don’t understand why he can’t be sympathetic of my feelings or considerate .
