My ex broke up with me almost a month ago, and said it was because he was leaving the country. After we broke up we still had feelings for each other, and would be romantic with each other. After that things just didn't happen none of us talked about what we were, and a lot of guys started flirting with me and he would get upset. Last week he told me he met a girl that he really liked, but told me this right after a guy came up to me and started hitting on me. This week he did the same thing, and was like I really like her I never felt this way about someone before I'm delaying my flight because I don't want to leave her. I got really upset and I don't understand why he's doing this to me.
