<human>: I met someone on Eharmony about a year ago. I love everything about this girl and think that I could have a great future with her possibly consisting of marriage.

The only problem that we have is we have very poor chemistry when it comes to personal communication. Whenever we spend long periods of time together we run out of things to say and end up sitting in silence for a long time.

It's hard to get her to give feedback on anything. When I comment on something many times the only thing I will receive in return is "That's cool", with no additional feedback whatsoever. Everyday I will ask her about her day and the most I will get is "It was ok" or "It sucked". I'll usually ask why it sucked, or why it was ok, then she'll tell me in a sentence or two and won't say anything else.
My girlfriend isn't shallow. She's very intelligent, has the ability to come up with great problem solving ideas, and knows a lot of in depth knowledge from a lot of different topics. She's just not very good at expressing herself or knowing how to ask follow up questions.

Some background information on her: She's been abused when she was younger, was in a verbally abusive relationship before she met me and has friends who are very self-centered and can be very hurtful. I feel that because of these things, my girlfriend has never been able to feel comfortable enough to open up to anyone about anything and because of which she has never learned to go deep in a conversation with anyone.

I would like to help her out so we can have more fulfilling conversations. The only problem is I am terrible at confrontations and I never seem to be able to word things correctly. This has caused many problems with my past relationships and has even been a huge contributor to many of my past breakups.
I would like to practice talking to each other more in depth somehow (suggestions are much appreciated) and would like to know how I should properly ask her without sounding offensive. If anyone has been through anything similar, or just has some advice it would be greatly appreciated.

Provide a brief overview of the text.
