<human>: Could you distill the essence of the text into 1-3 sentences?

I have posted before and thank you all for all the help and suggestions. 

I am now experiencing some other issues in our relationship and once again seek advice.

My girlfriend and I have been dating for 6 months and things have been pretty rocky but mostly do to my issues and insecurities but I am seeing a therapist which is really helping me so far. The biggest issue I'm experiencing now is the lack of affection she is displaying... my girlfriend would text me and invite me over and say I love you and call me pet names all day, all the time. I will admit I started to really like that level of attention she was showing. Now she isn't very affectionate or doesn't even contact me to the same level she use to. I feel this is just my lack of experience in relationships but I also feel she may just be falling out of love with me because of the rocky roads we have experienced. I don't want to leave without giving this relationship my all first. 

So basically, my question is, from what I said above would you say she is pushing away or this is a natural progression of relationships (just she is on a different page) or is she leaving me emotionally because of what has been happening? What should I do depending on her reasons.
<bot>: girlfriend of 6 months seems to be pushing away but I'm not sure if this is just me over reacting or something I should be worried about.
