<human>: Hey guys, 
I really dont know how to start this. I guess I just really miss my Ex boyfriend. I broke up with him a few weeks ago because I felt like certain areas of our relationship were lacking and that we weren't able to see eye to eye on a few minor things. I wanted to go meet other people and find out what love really is from other people. I felt like his touch lacked passion. 

He isn't the only one to blame for things, I have a long history of depression and anxiety and he's always been there to help me through it. I didn't make things easy for him and in the last 6 months due to my cat passing away I fell back into drugs and alcohol. I began pushing him away and breaking up with him on and off and generally being unstable. I would cut him down and be super mean to him. but that doesn't mean that i was like that all the time. I was going though alot of things and I felt like he wasn't there in the way i needed at the time. It's no excuse to treat someone like that and i know that now. 

we have a long history of abusing one another, he has put me through hell in the early years of our relationship and it basically ended with me turning it around on him. I love him so much, but he doesn't know if he want's to be with me anymore (which i don't blame him). he has found someone new and likes where it's going with her. he wants to see what happens instead of working it out with me (which again, i don't blame him him because i've done the same and understand i've pushed him to this point). How do i get my brain to stop thinking about him holding her instead of me? How do i let go and move on? I'm currently taking steps to be sober and see my friends. But should I stick around and let him see that i can be the person he saw in me all along? He said that he wouldn't be opposed to me making him fall for me again. I just don't know if this is gonna turn into old games again

Can you summarize the given text in a few sentences?
