<human>: So I was married from 2004-2011 (with a year of seperation in there, my ex had an affair, ended in divorce), I have a 5 year old daughter with my ex, and have 50% custody.  I met my current GF in November of 2012, we began dating in Feb 2013.   She's great, very kind, nurturing, thoughtful, my family loves her, my mom talks to her on the phone. (Never happened with my ex-wife). She's divorced and also has a 5 year old girl.  We laugh and have fun.  The problem is, we can't communicate with out the other one taking offense, and its gotten to the point where I have no motiviation to even have a conversation more than a few words.  She takes everything to the extreme, for example; 

Her: What do you want for dinner? (Tone: pleasnt)
Me: I don't care...whatever (Tone: indifferent)
Her: Well I guess I won't cook for you, if you don't care...(Tone: hurt/offended)

I don't take criticizm well and that is something I struggle to work on.

We get so many things right, but I'm still not happy.  She's galaxies better than any person I've ever been with, but I just can't shake this feeling of wanting to be alone.  I think I'm realizing that I was content with just me and my daughter...

Lately there has been talk about future plans, marriage (I want, she's hesitant), and how the dynamic would work out.   She's Chinese, and grew up in a very traditional chinese home, and I come from a family of midwest Irish farmers.   We have very different views on how the family should work out. 

I don't know if I'm just being an immature guy, and want to just be with my daughter. Or if this is really something to end things over.

Can you summarize the given text in a few sentences?
<bot>: Both Divorced with Kids, Different definitions of Family, can't decide if I'm a man-child or the relationship is getting toxic...
