Should men always wear condoms even if you're on birth control?

There's a man being shamed for not using condoms after his girlfriend of nine years baby trapped him.

Should men not trust their partners when they're on their own birth control and continue to use condoms anyway?

If you're on birth control right now, how would you feel about your partner insisting on using an additional method of birth control.

TLDR, these people have been together for almost ten years. She had had an IUD. His mom got sick and needs long-term care. He discussed both of them moving. She didn't want to, he planned on moving just himself. POOF! She's pregnant, and needs him and to be close to her family.

He just now learned she removed her birth control without telling him.

Some people are saying this is largely his fault as you should not leave all responsibility to the woman. He said he trusted her, but some people are saying that if you're a man and don't want to get your partner pregnant, it his HIS responsibility to wear condoms, point blame period. That men should ALWAYS wear condoms if they don't want to risk pregnancy. Your thoughts?
