<human>: Can you give me a shortened version of the text?

During my 2.5 year relationship with my ex things always seemed to be very strong between the two of us. We are both shy and we could connect very well together. Because we were both very shy and connected well we would spend the majority of our time together. Despite spending so much time together we never had any major problems between the two of us. 

Around the time we had broke up we had a few more disagreements than usual and she had broken up with me because she thought that I didn't care for her. I'm a shy person so I'm not the greatest with expressing emotions with other people. 

After the first couple of weeks she had said to me that she didn't want to speak to me or see me because she didn't want to be reminded about things because she thought that I was almost playing with her. I had written her a letter just to explain things which she only read the other day, and since then she has been completely different with me. She has told me she didn't realise how I did really feel towards her and was emotional about it. Only a couple of months ago she had based her University choice on our relationship just so things could work out between the two of us.

I'm just very confused about it all, so any help would be appreciated!
<bot>: strong relationship up until just before break up, first very vague at first with break up now she's acting a lot nicer towards me since I had written a letter to explain things.
