Summer romance YES or NO???

Over the course of a month I have been talking and sleeping with a guy (28 yrs old) who recently separated from his wife because she was a very controlling and manipulative person from what he told me ... I had been feeling realy guilty because I had slept with him more than once and I got severely depressed after the last time we had sex because before he left he told me that I was his output and I realized that this was just another friends with benefits and I'm all for it its just that I think I falling for him and I really don't want too because it's so complicated and I don't need complicated right now but I also love the summer adventure and how he makes me feel when I'm around him I don't know if I should end this before it gets to messy or if to keep going and enjoy the summer romance, please leave your advice comments below !!!!
