<human>: Can you summarize the given text in a few sentences?

So, a little back story. Just over a year ago I was at a conference in Chicago where I met this girl. We hung out for the one night, and we both returned back home: Me in Ontario, Canada, Her in Alabama. We have since spent countless hours texting, instant messaging and talking over skype. She has become very important to me and things have since gotten increasingly difficult given the distance. There is a strong mutual connection emotionally that is evident, however it being long distance I'm filled with uncertainty, which is amplified when communication seems staggered. I've made suggestions to finally see each other which are met with hesitation. I have had to personally halt contact for approx. a month just so I could re establish some emotional stability which she met with great concern and apparent relief when we finally reestablished contact

There are more details which I could elaborate on if this receives any attention.

My question is how do I go about this? It seems like for a few weeks at a time all is well. We are always talking and the relationship seems to be very mutual. Then suddenly communication becomes lagged and I don't hear from her, or my messages go without a response. I love this girl dearly and we relate on so many levels, but I can't think clearly when I get to points of uncertainty and it impacts my work and social life here at home. Its become an emotional rollercoaster that's become difficult to deal with. So should I try and confront her with my concerns? I honestly don't know how to approach this situation, and could use some advice from someone with a similar experience. A female perspective would be extremely helpful.
<bot>: In long distance relationship that feels erratic. One week warm and mutual, next week SO feels cold and distant with delayed contact.
