Would you be mad if your SO spent more time with his friends then you

Okay so lately me and my SO have been going through a lot. Just a lot of fights here & there. And i just get kind of mad because he spends more time with his friends then me. I go to school and work. I don't really have friends. But i always give him time with his friends and try not to bother him. Sometimes i don't even text him when he's with them, because he would suck at replying anyway. Well i know he has a lot of stress on him. He's going to boot camp in a few months and his mom is apparently dying from her brain tumor. As much as it bothers me that he hasn't been trying to spend much time with me....i haven't really brought it up. We both don't have very good transportation to see each other, but i know he has a better way of getting to me then i do to him. So i figure, if he wanted to see me he would. I just feel kinda sad though because he worked all day and i only talked to him on the phone once. And now he's busy with his friend.
