My ex boyfriend was high and said he loved me..

Last night I was hanging out with my ex boyfriend and we were really high. He was in a part of his room away from me where I couldn’t see him and he said I love you. I said back “what did you say?” And he said he loved me again. He said it several times. I then asked him “if you love me then why aren’t we together” (we broke up about a month ago) and he didn’t respond, but then I thought I heard him crying.. I don’t know what to think or anything. I just need some help
