I have been dating this girl for 6-7 months, and I'm starting to worry about the way I act. We're both 18.
My being clingy certainly isn't something I've been accused of, because even if my girlfriend thought it I doubt she'd be inclined to tell me about it. I've observed that I'm emotionally clingy and while it's something I that know about, I don't seem to have much power over it.
She is inherently passive by nature and doesn't really drive the relationship - I can work with this, despite it not being ideal. Consequently I'm the more affectionate/romantic/intimate member of the relationship. This isn't a conclusion I've come to on my own; it's something she agrees on - it's also something she has no power over. While I'm at peace with it, it can result in clingy behavior from me. I'm consistently seeking reassurance and can't bring myself to ask for it, because it doesn't feel legitimate if I do - so I'm left somewhat frustrated when she doesn't understand.
It's currently something of an issue because she's a few thousand kilometers from me with her family for Christmas, and I won't see her for a few weeks - it's really shining a light on the problem. I recognize that it's largely my insecurities that are to blame the situation, so I'm left wondering if Reddit has any advice for reducing my clingy behavior?
Apart from this one problem, our relationship is solid - if anything's going to end it, it's the way I act.
I will provide any additional details upon request
tl;dr: I'm very emotionally clingy and can't seem to work past it, despite a relatively fulfilling relationship with someone I care a lot for. Any advice or insights regarding this kind behavior and how to get through it would be hugely appreciated.
