So for context we're both at university in first year, we met fairly on in the year (first 2 or 3 weeks), we clicked instantly and started dating very quickly. I've never clicked with someone as well as I have with her, we have a really good relationship, there have been a couple of minor issues come up but we're both very open and make sure we talk to each other about things and if anything does get up it's resolved very quickly. The only times we have had somewhat serious things come up have been because one of us hasn't completely considered how the other felt in situations which we always sit down and talk about and make sure we understand the side.
So in that sense, we're quite mature about things and are good at talking things out, however since the very start of the relationship we've stayed either at mine or hers every night we've had the chance, the only time that doesn't happen is when one of us is away at home or whatever. It's been lovely to see her so much and I enjoy spending nights and evenings with her, but it's quite full on. I've always thought that it's a lot for us to do it every single night but never said anything about it. The thing is, I feel like sometimes I miss out on just small things like cooking dinner with my flatmates in the evenings or just having a chat to them at the end of the day which I feel is part of the experience of being at uni, especially as I am very fond of all of my flatmates.
Secondly, I have exams coming up and though I can try and sleep early and get up on time when with her, it's inevitable that I'm going to stay up later and be more tired when I really need to be in a good routine of work right now; we just always end up doing something or other and staying up late most nights. But lastly, I feel like I'm a person who enjoys their own company quite a lot; I love a quiet evening to myself every now and then, cooking dinner for myself then maybe playing some games and going to bed and being at uni now seems like the first time in my life I've consistently had the chance to do that with my own room and living space.
Having said that we are very able to talk about things in our relationship it seems like it should be easy for me to bring this up, however I'm not so sure it will be. She has become quite attached, and I'm not saying I'm not, but not as much as she is. She's told me before that she'd be sad if I didn't want to stay the night with her anymore, and always tells me how much she'd rather I was there when we're away from each other. The problem is l've never mentioned anything about this to her before, over 6 months into doing this, and so I feel like if I bring it up now I feel like she'll think something is wrong or I'm not as into the relationship as I was before. I don't want her to think this because I love her very much I just think a little bit of space might do some good, I'd be quite happy if it was just 1 or 2 nights a week I was on my own, just a little bit of time.
What's the best way to bring this up to her without making her feel like there's something wrong?
