Wedding band & untruthful husband

My husband & I had a stressful week leading up to the wedding & hadn't organised wedding bands (family, time constraints, work commitments, etc).

Anyway we discussed how important it was to me & he said he would get a band after the wedding, we would get the rings blessed, etc.

Fast forward 4 months later & I said to him today 'lets sort it this week'. Cue explosion.

'It would be a symbol of resentment'.

Followed by 'I lied. There is no way I would wear a fucking wedding band'.

I can't believe he lied. I supported him on keeping our pregnancy a secret at the wedding, him spending a week away when I'm 36 weeks pregnant. I wonder what else he has lied about. I feel so betrayed.

What do I do?
