So I met this guy in college. He was really interested in the beginning and we would talk everyday. We went out a couple times and I really felt a genuine connection, which made me go head over heels for him. After a month, we had sex, but then he began putting significantly less effort and even though we kept a snapchat streak, he only talked to me when he wanted to hook up with me. The situation turned into a breadcrumbing chaos, were he would reach out whenever he saw that I was pulling away and give me the bare minimum to stay interested. I was really into this guy so I kept up with the situation for 2 months, and even tried to improve our relationship by texting him more and planning to meet up more often, but then a friend spotted him on tinder and I took this a sign to get myself out of the situation. We never discussed exclusivity and didn’t have a label, but he made it seem like I was the only one he was seeing so that I kept having sex with him. I cut communication off with him with no explanation, and we have not talked since then. Was I wrong for cutting communication and not telling him why?
