I'm 18 and want to sleep over my boyfriend's house but I think my mom is against it?

I turned 18 two weeks ago and a senior in high school. My boyfriend lives an hour away from me. Sunday, he's moving back to his original home town that would be two hours away from me. So we'd see each other even less. He works, I can't find a job. My state has horrible employment. Anyways, he's moving back to his home town until he goes to Army boot camp in early June. I'm going to Navy boot camp in October, possibly sooner if I push to get my date moved up. So this is one my last few times to spend time with him, you know?

I'm a responsible girl. I don't lie to my parents about my whereabouts, my friends are dropping and failing out of school like flies and I go every day and do my best. I'm going to be doing something with my life. And I feel like I've already made the most "grown up" decision I could ever have made when I joined the military. So I think I'm old enough to spend a night at my boyfriend's house and come back in town the next morning.

I'm not going to his house to have sex. We haven't even had sex. Like I said, this will be one of the last times I have to see him. We're both going active duty. And he'll be back for a week of leave, I think, right before I go to boot camp. And when I get out of boot camp, I probably won't get to see him on my leave. And to make matters worse, I'm doing a seamen apprenticeship so I'll be on a boat for a while getting hands on training with all the jobs on the boat.

So I just want to sleep over my boyfriend's house before he leaves.

I haven't talked to my mom about sleeping over a guy's house while I've been 18. But I know she disapproved when I was 16 and 17 saying I was too young, even if they were just a friend. All of my friends are guys, so I never got to sleep out.

I know that I'm 18 and legally I can, but I'd feel much better about this if I could convince her, instead of just doing it. I respect her opinion and whatnot, but times have changed and I'm a good kid.

Any help or advice would be greatly appreciated.

I really don't know how this got into sexuality when I put it in relationships...
