<human>: Hi,

I[19m] split up with my first serious girlfriend nearly 3 years ago after she broke up with me, I've had multiple girlfriends and partners since and I'm currently in a reasonably long term serious relationship now that's been going on for 6-12 months and I believe so is she. 

I don't still speak to her, she's off at university so I don't still see her and I don't have her on Facebook but I can't for the life of me forget about her. I still haven't gone a day without thinking about her. I still dream about her and wake up with my stomach hurting to the point where I struggle to get out of bed. 

Even if she did want me back I'm about 90% sure I wouldn't go back out with her because I love my current girlfriend and I don't think it would work between us because towards the end of the relationship I wasn't too happy and that's what led to the breakup.

I'm not entirely sure what I want from you reddit but what can I do?  Is this normal?  How long is it gonna be before I forget about her and how can I make this pain stop?

Thanks in advance for any replies.

Can you give me a shortened version of the text?
