<human>: Can you condense the text into three sentences or less?

I'm in relationship that's just over 6 months and a friend of mine just sent me my gf's profile on a dating site (that he is frequenting). She used her own email address so I'm sure its her. 

It's been an OK relationship since the beginning, we even met each other parents during the christmas (I went to hers, she came to mine).

The relationship has a kind of a rough patch right now (she's writing her dissertation paper atm so shes fully comitted to it and I'm kind of needy because of it (I nag her supposedly pretty often, recently stopped doing that though - i understand she needs peace and time to write it and the deadline is soon).

The problem is - what do I think of this profile? On the profile (foreign language so im translating) she says "from my not-so-many relationships i understand im high maintenance, and my relationships are usually a burden rather than enjoyable experience, but maybe its just a matter of not having found the "prince charming".

What do I do? How do I approach her about this?

On one hand I don't want to make a mess now that she's busy with her paper (and it means a world to her), but on the other hand - I'm shocked and feel like crap, I can't believe she's put up a profile on a dating site.. She's never said that anything's wrong with "us", but I can feel that there's some "tension" ? I thought It was related to the fact that she's extremely busy, but if she's got time to create a profile on a dating site..... Friend of mine suggested that I should create a fake account and flirt with her, see what her intentions are.
<bot>: just over 6 month relationship, gf created a profile on a dating site and is somewhat avoiding me (probably due to her lack of time but not necessarily).
