So my girlfriend (19F) and I (19F) have currently created a pretty flourishing relationship. For the foreseeable future I don't see us breaking up (we see eye to eye on A LOT) and we are both heavily attracted to each other. However, I have built most of this attraction via the whole 'embrace the space', 'act like you don't care', kind of gambit. For example, I will always wait until she texts me to reach out to her, if I ask her out and she's busy, etc. Then I don't mention anything until she wants it, etc, etc - basically I let her come to me and to avoid feeling bored in the meantime I keep as busy as possible with self improvement, doing the things I like, etc.

Here's the problem though: I'm getting the vibe that SOMETIMES - not always - she feels very de-validated by my actions, and maybe even feels to an extent that I don't care about her. Which I do not want her to think because that's a very negative mindset for her to be in - and since I actually do care about her, I don't want her overthinking things and hurting herself emotionally. She constantly asks me if she's being too clingy, or if she's annoying me when she texts and calls me, or seeks me out. For clarification sakes - I very much like the reaffirmation these things bring, they make me very confident about the relationship so I wouldn't trade them in for anything.

She'll often say things like "I miss you", "I wish you were with me right now", etc and while every part of me wants to return the notions back at her I have been taught - to an extent by this sub - that telling a girl things like "I want to kiss you right now", "I miss you", etc show a type of weakness and neediness that girls - while they may find gratifying in the short term - ultimately end up unattracted by as a result of a lack of independence, neediness, etc.

So, is there a way I can put her mind at ease while also building attraction? I don't want to 'over-validate' her to an extent where she no longer values my opinions/emotional sentiments but at the same time I don't want to not validate her and have her unhappy/feeling like I don't care about her. What is all of your happy mediums?
