Every commenter who doesn't understand what she could mean by saying that has never had a clingy significant other. As someone who has been in her spot, lay off a little bit, OP. Not everyone is into constant attention. She may not be the same as me, but I've said the same exact thing in relationships I've had, and that's what I've meant.

How the **** is this his fault?

dump her ass

Dump her, and why does this have more YDI than FYL? Oh right, when it comes to relationship troubles, who`s to blame? The man...

What's with he YDIs???

I think what she means is to scale back your outward expression of your love for her. That is something that I occasionally ask my boyfriend to do. In the beginning of our relationship, his dedication to me seemed borderline obsession and it really freaked me out. Needless to say we had a serious discussion about why he did all of that, and about what behavior is appropriate- especially in front of family or friends. I recommend having a similar conversation in which you can both explain your feelings and perspectives BEFORE deciding whether to continue or discontinue the relationship.

How, just how, does OP deserve it?

Sorry, OP, that's not a good sign. But at least now you know where not to waste the love you have to give so you can save it for someone more deserving.

Has no one heard of aromantics or, god forbid, people who struggle to love due to trust issues? If a man said he was struggling to love, it'd be normal, but since it's a woman she's suddenly not worth the effort? Honestly, some people have different capacities for love and if someone experiences love a lot more deeply than their partner, it can make a partner feel awkward and guilty. That doesn't mean they don't love them, it means they experience and express love differently. This isn't counting in for time, some people takes a very long time to come to term with something like love.

I've never thought of affection as an arms race... Sounds like the Cold Love.
