With regard to seeking his help in understanding and dealing with your emotions: it seems that you are seeking something that he is not capable of providing at the moment.

I agree that you seeing a therapist individually could help you recover and heal. If he were willing to try to overcome his insecurity and defensiveness, he would be wise to see a therapist individually as well.

It sounds especially awful to me that he expresses so little interest in seeing that you get help for dealing with your traumas, including particularly the recent one. "Forget about it and move on", plus taking offense if you don't, are not appropriate responses to a loved one's trauma.
