<human>: Just like the title

Great relationship, but recently she stopped answering texts sometimes. Weird. But I am not a clingy guy so I dont pester her, I just wont double text. Every time this happens (at least 20 times) she will text me back an hour later asking about something and being extra friendly. It feels like she wants to start a conversation, but then she goes back to being distant over text. She also has tweeted or used other social media while not responding to a text from me. So obviously she ignored the text.

Texting may not seem like a big deal, but now theres the sex. We have a lot of sex. But she recently decided that period sex was not her thing. I will not push this though because its completely reasonable to not want to have period sex even if I am 100% okay with the mess. But she didnt have an issue with it a few months ago. She suddenly did.

Its a bunch of little things I fear will lead to a breakup. In general, I feel she doesnt appreciate me enough. Of course I have thought of talking to her, but as weird as it sounds, I feel like thats very clingy. I want to tell her to appreciate me more, but thats not the right course of action because appreciating someone cant be forced.

I really feel like shes losing interest and I know from experience that putting more effort into a relationship may be counterproductive as it smothers her. Part of the issue is that im the kind of guy who is too available. Ill rearrange my schedule to hangout and go on dates. I do not do it because im clingy, I do it because its easy to find the time (even with school, work, and friends to maintain).
 
Anyways, is it too late to save the relationship and should I break up? Im lost at what to do. All I know is im becoming less satisfied with the relationship and I do not want to waste time with this girl if she isnt willing to put in the effort. But id like to try to do what I can to fix it first.

Give me a shortened version of the text
<bot>: Girlfriend becoming seemingly disinterested due to the way she texts, acts on dates, just in general. How do I fix this without being too clingy or too distant myself. I feel unappreciated.
