Bf guilt tripped me into having sex without a condom

Bf guilt tripped me into having sex without a condom even after I said I didn’t know where in my cycle I was, so It got to my head and now I feel bad when we do use protection bc I thought it made him feel bad that I wanted to use a condom. So this most recent time, we had sex and I said it was ok to not use a condom and then after he said it was scary and that I was trying to “trap him” and now I just feel low class. I was not trying to do that at all, I just wanted him to have a good time and feel desirable. What do I do, who is in the wrong.
