Is this a red flag?

I texted him “ Why do you even want to marry me? I mean I don’t think I’m a normal person (because I have really bad social anxiety)” and instead of giving me any reassurance he said “Well what do you want me to say Why are you asking me that almost 4 years later Like I don't know what else to say lol Like I already have the day I'm going to propose worked out... I've had it worked out for awhile “ and then he told me good night and that he loved me and didn’t answer my question at all.
