Me and my girlfriend have been dating for 8 months now. Things have been going amazing up till about mid-February. We see each other alot, its been that way since we started dating.

Here are some notes:
-She's 21, I am 19.
-She's very faithful, she's been cheated on 2 times, never cheated on anyone. And talks about how she would never do anything to jeopardize our relationship.
-I trust her alot and she trusts me alot
-Weve never had a fight, weve argued but when we do, we always forgive and forget and work things out before we leave each other for the night.
-I give her orgasms consistently and they are damn good.
-For Valentines, I got her a promise ring and she loved it, we made a promise to work together in tough times, to be loyal/faithful, honest, and that an engagement is in the future.
-Shes talked about marriage with me alot and sometimes I think I put that girl in a damn trance she is like in a dreamy state and talking about if I proposed right now she would say yes haha.

Basically, on a normal week, we will hang out on Monday (usually a full day together), see each other at school Tuesday then she works, not Wednesday (she works, then schoolwork), Thursday we go out for lunch after school before she and I work, Friday is usually a full day too, Saturday were not together cuz she works, and some Sundays we go out for yoga were together a few hours.

Thats our usual week, now sometimes it gets a little cramped because of exams or her having to work more. I only work three nights a week, and with her schedule, its not taking away from our time together. The only free time/days she has, we dedicate it to us being together and doing fun things.

Now recently, a few issues have arisen. For one, she sometimes gets mad at little things (once a week, no more than that). Two, she's noticed I am not acknowledging her parents near enough, (sometimes I just walk in her house like its mine, ya im at fault). Three, our sex life/intimacy has decreased or been in a lull. (We used to have sex 2 to 3 times a week. Now we have only done it 1 time in almost two weeks) This could be due to how stressed out she is at work, plus we dont have less time together as of late, cuz of school and she picked up some shifts. She told me that thats why its decreased, not because she doesnt want me. Four, she doesnt really initiate things, unless getting into bed naked without me asking and then grabbing at my penis means she wants it and I am overlooking or expecting more.

Sometimes I read shit on this website and I feel like I may not be doing my job right as a boyfriend, and I have a little anxiety so I worry excessively and maybe about irrelevant things. She shows lots of PDA (hold hands, hands around waist, kissing me, whenever people at school walk by that she knows she grabs me with both hands lol and kisses me). She wants to progress our relationship always. Our sex life has lulled but she still gets really into it, maybe Im not initiating enough, or TAKING WHAT I WANT! I get the feeling I am doing a good job, but I need some guys more experienced to read this and let me know what you think, this is my first serious relationship. With her work schedule, I cant really play harder to get in terms of hanging out with her, we both have to take whatever time we have :/ so what are other ways I can still keep her just as interested as she is now, forever? I do neg her a little bit, im a hilarious guy, I do a shitload of nice things for my babe, and I am pretty damn close to the perfect BF.

Thanks for the future feedback! I appreciate it, I will reply to all, hopefully this can be more of a discussion.

PS- I was thinking, she just said she was afraid I might get lazy in the future, and if we get married I wouldnt follow through with my orthodontist goal...Hmm, maybe I am not working on my life goals enough and showing her that I am a determined individual. So I was thinking of meeting my orthodontist for lunch someday, and telling her that I am doing that, and how it went Would that show her a little bit that I am serious?

THANKS!

Heres how a normal morning goes lol.

Me- Good morning babe, wake the fuck up
Her- Good morning snookums! Im freezing balls in bed! Ill see you at school later, okay babe?
Me- Do some jumping jacks nude! Sweet, Ill see you then.
Me (Random)- Whatever you do, dont wake up nude someday and take a pic in that mirror
Her- I was thinking about it lol
Me- Hot damn! So, Im making out with you at school today when I see you, not just a peck (im not a bird lol), so you best be ready for some PDA, aka face-suckin gurl!

IDK, were just playful with our texts and shit. It gets better than this Thats a good sign after 8 months, I mean, were not bored with each other.
