I am a nursing student and let me tell you I study all the time and still don't have enough time. You have a good man but you are being selfish and immature. your title asks do you love him? If you can picture yourself with anyone other than him then no you don't. If you truely loved him and wanted to marry him you would be supportive and know he is working toward a foundation needed to have a life and family. Sounds as if you have a good man but i'm telling you if you don't grow up a little someone else will get him. Good men are hard to find. Do you work are you In school? Occupy your time. You should have a life and he should have a life so that you can share a life together. What fun are you to him if you do nothing but whine and nag him. I understand it is hard when you want more time with him. I too have a boyfriend who has 3 jobs. Time is scarce but we enjoy the time we have just because we are together . just try a different approach .  When he works a third shift we meet for maybe ten min in the morning for a kiss many times on the side of the road as we cross paths. 10 min its not a party its a good morning i love you have a good day and kiss good bye. It helps stop some of the lonelyness of not seeing each other at all.  If you know he is busy don't distract him by lingering around and staying longer it will hinder his time and make him not as open to meet up for a few min. next time. Good luck. Hang on to a good man.
