Please tell me what you think

My boyfriend and I are ttc before he leaves for navy boot camp, and he wants to get married before he leaves as well. I will be 20 next week and he will be 22 on Christmas but I am still in college. Do you think this is a good idea? An should we tell our parents before? He doesn't think we should until he comes back an we have money for a full wedding, I mentioned it to my mom a while ago an she said finish college so I'm scared to tell her if we do it. Please tell me what you think
