Pushing away?

My husband and I have been married a year and a half now, and I recently feel like he’ll push me away or he’ll withdraw if we have a disagreement about anything. For example, I went to the grocery store earlier and I bought pudding for us to pack in our lunches. Later on, he started making gagging noises and joked around saying he wasn’t going to eat it because he wants to cut out dessert . But after I told him that hurt my feelings, he got upset with himself and he withdrew from me and didn’t really speak to me before he went to bed.

Sorry for the long post, but he’s never behaved this way and I feel like something is my fault.
