Should I be mad?¿🥺

Lauren

I like this guy so much and we are talking (he wants to date but hasn’t asked me( and we are always talking on the phone and flirting during class and stuff but on a day he told me he wanted to give me his jacket he never did but at lunch I saw none other than his ex wearing it and I have no idea what to do. Should I be mad and not say anything or should I tell him it made me mad and see what happens.
