<human>: So at the beginning of this summer , I (20m) went on a few dates with this super nice girl (let's call her E). E and I got along well but she was pretty busy and we did a fair bit of chatting online but stopped going out for about two months. Then she messaged me saying we should talk and saying she was sorry for being "emotionality unavailable". So I agreed to. A few more weeks passed and I tried to make plans but she wasn't free and now eventually she is free. The thing is I am not interested in anything long term because I don't think I'm ready for that kind of relationship again (my last one was really bad). 

 when we hadn't messaged eachother in a few days, I made plans to hook up with this other girl. Which is supposed to happen tonight. I don't know if I should call it off/it would be hurtful to e. Or if I should at least talk to e first.

Can you condense the text into three sentences or less?
