<human>: Me and my ex were together for 2 and a half years, and she was my everything. 

I know I'm only young and alot of people will tell me I don't know what I'm talking about, but she was my first love and to some extent I still love this girl a huge amount.

Me and my girlfriend broke up, because we had gone to separate university's and it was really hard not being able to see each other (especially as we both have demanding courses).

6months ago we ended things. We ended things over the phone, but when we were both home (a few weeks after) we met up. We exchanged belongings, and cried and talked, but we decided it was for the best and ended on good terms.

Here is where the 'problem' lies. When we ended things, I told her that I would be too hard for me to keep in contact with her. I blocked her on Facebook, and all other social media, along with deleting her number.

Although this may seem cruel to some of you, I honestly think this was the best course of action for both of us. I don't want to question every time i see a picture of her with a guy, and vice versa. This girl was my first everything, and the thought of her with another guy still really upsets me.

She told me she understood, but would really like to at least remain in contact. I told her I would message her in about 6months, at which point she got very upset and said that it would never happen. I said I would do my best.

6months have passed now, and although I am alot better now, I an definitely not completely over this girl.

I don't even know if she would want to hear from me? And I don't really know what I would say. I feel like I kind of owe this to her, but I'm worried it might set me back a bit, in terms of moving on.

Any advice would be really appreciated. I'm at a bit of loss.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Broke up with my ex and haven't spoke to her in 6months. Should I contact her, just to let her know how I am, and see how she is?
