<human>: Can you provide a brief overview of the text?

[23/M]I broke up with my girlfriend [22/F] this morning from a 4 long year relationship that has gone through fights, fakebreakups, threats, and lots of jealous thoughts (for small scale cheating reasons). But I feel like this was the one girl I could marry for all the time and romance we had between us.

But the point of this is that I have two tests and I can't even stay on topic without feeling like I'm being weighed down by all of these sad emotions.  I try to buck-up but in the 10 min I get happy I just get pulled down even deeper.
<bot>: I need tips to continue not thinking about my relationship so I can move aling in my life. Whether it be advice or a small story that relates. Thank you.
