<human>: Well, this is not easy to write because I feel incredibly stupid. Over a year ago I broke up with my ex of 1 year because I felt I wasn't in love with her anymore and it wasn't going to work long time. I had second thought every now and then, but now that I've dated other girls I think I realize that I didn't appreciate what we had.. 
I met her a couple of times at university and I thought about her every now and then, but now close to graduating with my masters I think about her a lot more often. I also think that her introducing me to her parents back then was kinda a thing for me because it scared me in some subconsciously immature way. 

She took it very hard, which made me take it very hard and every time I was tempted to contact her I thought about how devastated she was when I broke up and that it would be wrong to stir it back up. But now I think I actually want her back. I think I want to give it a real second chance. I think I changed how I think about the future and what is important.. I am thinking of writing her how she is doing and if she wants to grab a cup of coffee sometimes.. I don't know why I am even writing this here I should leave her alone I guess and seek out something completely new, but after dating so much I am not sure I even can fall in love and maybe I should settle for someone I like and am comfortable with instead of searching for something surreal.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Contacting my ex 18 month after I broke up with her, should I do it? I think I want her back.
