I can’t cope

So the boy I have been seeing for little over a year ( we have been dating for a couple of weeks though) has asked me to meet his mum but it makes me uncomfortable because I have a fear of commitment and this is just too much . I do like him I just don’t want to be 17 and pregnant and never able to go to uni or college without worrying about a baby (we haven’t done anything I just I’m worried if we do)

Can anyone give me advice because I’m not ready for commitment
