Ex freaking out I learned the truth

So we broke up in September, she message me late at night like 1:30am and again today at 10am cause someone were both friends with told me something and let’s just say it’s fuck up she had a dude in her dorm not even a week they kiss cuddle and she watch him played games and she thought that was hot I learned this yesterday. In October I learned she got cracked by a one of these guys she slept in her dorm cause apparently her girl blonde friend invited theses guys like obviously I saw something coming at that time the sleepover happened three day before the break up. She also goes to 1 to three frat parties. Also smokes. She even lied so many times cause she was worried I would leave her if I knew she smoked and drink alcohol. I didn’t know the alcohol part till her parents told me at a restaurant. She lost feelings because I didn’t kiss her and we had quiet and awkward moments but that was all on her she’s indecisive and I talk all the time. There’s a lot more the relationship was only over a month. But we’ve been talkings for 3-4 months before dating. But since college came everything changed.
