<human>: Can you give me the gist of the text in a nutshell?

hi reddit,

i'm so stupid!

my ex-boyfriend (26) and me (f-24) have been together for 5 years, but broke up about 7 months ago. 

my friend told me, that he just recently started dating again. i thought i was cool with it, but apparently i'm not. 
i knew that yesterday he was going to meet some of his mates at a pub, so me and a few girlfriends went there, too. we pre-sipped, so i was already a little tipsy when we arrived. i acted surprised meeting him there. 

we talked, and had a few too many shots of Jager... 
we left the pub, and went to his place. i spend the night, we had sex, and this morning was just too weird. i apologised, for my actions. i told him that i can't handle the thought of him being with someone else. he said, that i was the one who wanted the break up, and that he needed to do a lot of thinking. he then asked me to leave... :(

i'm usually not like this. i would never ruin a relationship out of jealousy. and i would never make anyone drunk to have sex with me. 

i just realised, that i miss him, and that i still love him. i don't want him to have another girlfriend. when i broke up with him, i thought it was for the better. even though we lived together, we barely got to see each other, because we were just too busy.
he wanted me back, texted me, called me, tried everything, but i just had this stupid idea, that perhaps we were better off without each other, and that i didn't love him anymore... 

but that's not true! i still love him more than anything.

i know that probably none of you can help me with this, but i just needed to tell someone!

thank you for reading... <3
<bot>: miss my ex. thought i didn't love him anymore, but still do. we both got drunk last night and had sex. what to do?
