<human>: It has now been a month since I broke up with my ex and I really can't stop thinking about her. The relationship was long distance and only lasted for 3 months but we had been friends for 6 years, altho we were not talking for a while before we got together again. 

Even though it only lasted for 3 months, I have more trouble getting over this relationship than I have ever had in the past, mainly because of the fact I have always liked this girl but for the longest time accepted I probably would never be with her. 

When she made clear she wanted to try it we got together and for a while everything seemed perfect, she would always want to talk and even be kind of clingy which I actually liked but after about 2 months, she suddenly got extremely distant and would never talk to me first and only reply with a few words and very delayed every time I would text her.

I asked her a few times in that month if something was wrong and she would always say no, after I asked her 2 times in 2 weeks time she got very annoyed and told me to stop asking her if something is wrong.
 
After 2-3 more weeks I decided to have a conversation with her and that's when she told me she didn't want it anymore, the reason she gave me was that she felt we "fought too much" even though I never had the impression we did, she basically told me I annoyed her by not giving her space, I did my best to do that even not talking to her for a long time so I feel this is not the real reason. I have been feeling very bad about this because she was a good friend before and I don't know if I can stay friends with her now that it has once been more than that altho when she broke up with me she insisted on staying friends.

Give me a shortened version of the text
<bot>: girlfriend suddenly got distant and broke up for no apparent reason, unsure if I should just ler her go and if I can stay friends with her.
