<human>: It was my first experience of love but we ended up breaking up very quickly after the first month she moved to university in 2011. 
I had a fear she was going to break up with me at the time. One day she asked me to fix her laptop for her and I decided to write stupid statuses on her facebook while she was still logged in. Then a chat window appeared from her friend and I read how she (my ex) said she felt bad that her and all of my friends had went to university and I was left behind, and that this was the only thing making her feel guilty about being single again. After reading that I became full of emotion, I felt like i was stupid for loving her and I broke up with her a few days later over the phone saying that I didn't want to hold her back (but mentioning that i read a private chat she had with her friend on her facebook).
In the following year I was very low-key about how hurt I was. It wasn't until a year ago that I formed my first new relationship since then (that I am currently still in).
The reason that I feel like I need closure is that I think my previous relationship experience is preventing me from loving the person I am with now (or anyone else for that matter).

Should I clear up exactly why i broke up with my ex?

<bot>: bad ending with ex of three years is stopping me from loving anyone else because now I am afraid of getting hurt again.
