You already know what comes next. Likely a fight of some type with some name calling and then he will cycle into love bombing and disbelief/denial about your feelings.

It's just a guess on my part. But he will likely act similarly to past behaviors and major stress events. Is his pattern guilt trip, angry outburst, love bomb, denial, short period of quiet and then back into guilt trip its like a tornado... always spinning and churning but you never know how much damage it will do.
