Am I wrong? I don’t think my bf cares

mimi

Hello everyone so I’ve been with my bf going on 2 years and I’ve known him since 2015 when we graduated high school anyways, I’ve seen how he treated girls in high school the Romeo type. Well while I compare our relationship I think I’m getting the bad side of him so last year for Valentine’s Day he took another girl out and bought her some items and I was calling him all day and crying he didn’t even really reply to me until 1 am I found out he took someone else out a week later left him and got back with him. Fast forward this year he said he was working and that Valentine’s Day is just a day but I had explained to him if it’s just a day why did you do what you did last year and he got mad at me….. is this a red flag?
