<human>: Can you provide a brief rundown of the text in within 3 sentences?

We've been dating for about 6 months. I recently did some Facebook stalking and stumbled upon his ex's profile. They had the cutest pictures together and really seemed to complement each other.

They also looked so happy, and they would often go out with their friends, and their families were very close. He lives in a new city now, where he met me, so I don't know any of his friends or family. It makes me feel disconnected from that part of his life, or like I don't even exist to them. 

I don't know how to get over their relationship. It makes the one I have with him now seem so bland in comparison. We don't take that many pictures, and because of our busy schedules, I only get to see him a couple times a week.
I just wish we could have the relationship they had, going out and making memories all the time. I can't stop crying. I wish I'd never found her facebook. The only reason they broke up was because of distance, which makes me think they would've stayed together otherwise.
<bot>: I don't know how to get over my boyfriend's past with his ex because they seemed perfect and happy for each other.
