<human>: I don't really have anyone else to talk to about this and I need another point of view on my situation. I'm currently in a 2 year long distance relationship (California - Texas) However I have known my girlfriend [26/f] for about 12 years now. We dated in high school for about 2 years and then got back together about two years ago. 

Now to the problem..
I have a social problem and she knows this. I have issues with holding a conversation. I'm able to answer questions without any problems however I never know what question to respond with.

This past Christmas I spent it with her family everything I thought was going fine and went fine until I got home. She was upset that I did not talk to her parents enough and only had 1 sided conversations. I thought I did better however it wasn't enough to her expectations. She also thought some of my answers to questions weren't the best answers. 

Now after we talked about it she doesn't feel like I tried to change in talking more and that now I'm giving up by not willing to change.

I feel like the relationship is over. We barely talk now and when we do I feel like shes so upset with me she doesn't care about anything I have to say. I was going to marry this girl and now I'm just completely lost and confused why someone I loved so much and I thought loved me would leave me over a social problem. 

Any comments no matter how rude or harsh will be greatly appreciated.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: b/f has social problem, g/f leaves b/f over inability to socialize with g/f's family.
