Plate, fwb for 1 year and ltr for about 5 months. For the last few weeks I feel like I'm giving off a comfort vibe more than an excitement vibe. I used to be more colder I guess, now since we know each other better I think I kind of let loose a bit. I could easily persuade her to public before, while now she rejects it. She is preparing for the national uni exam so she's busy, hell she even switched her phone to those call-text stone-age phones in order to avoid the distraction of the internet. (before someone says something about this, its common for uni exam students) She texts me rarely, usually just before the time we usually meet to check. I think I'm going too stable and as my physic goes I look small and even though I was being the best man I could, there is a tendency to slip into the beta zone as I am not big. (180 cm, 70 kg, I feel very small, going to the gym since 1 month). How do I spice up the relationship? Is she actually losing respect or am I overreacting?

(I dont know if this detail is important but, she had told me that some guy hit on her in her school, to which I had replied "ok, i trust you." then switched the subject. You can see that post in my history.) [Deep inside I'm pissed and making scenarios in my mind,]

TLDR: How to rekindle a relationship that I suspect is going too stable?
