<human>: Give me a shortened version of the text

My boyfriend and I have been together for a really long time. Our relationship wasn't the best, we had lots and lots of fights and arguments, and that really took a toll on both of us and we broke up a year ago. 

But the breakup was really messy, he said he really loved me and cared about me; and there's a part of me that just can't stay away from him. So that resulted in our on again off again relationship for a year. During this time, we would hangout, fight, then leave each other and this vicious cycle just keeps repeating itself. 

He made me really depressed, but a part of me feels like I need him, after all we've been together for so long. He recently texted me again, and told me that he misses me. I couldn't resist temptation and texted him back. 

Of course this all ended in a fight, and it makes me really really depressed. And it hurts me to see that he's happy even though I should feel happy for him and just move on. I know it sounds really stupid, but at the moment I feel really stuck and I would love some advice from people with similar experiences.
<bot>: Troubled relationship with long term boyfriend. Had a messy breakup which resulted in an on again off again relationship. Need advice to get out of it for good.
