I know I'm not in the wrong!

My FWB and I are now more serious for the past 3 months. He told me I should throw away my condoms because we don't need them. I said why would I throw them? I spent money on them. AND what if I want to keep wearing them when I'm on my fertile week? He got upset and it's annoying I'm defending keeping them. We even woke up this morning and he was still upset about it. He had to leave anyways to do something but he slammed the door. I felt it was a red flag he's not respecting decisions about my body. Not to say I don't have my own red flags. I just don't see why I would need to apologize if he's leaving like that
