BF accused me of trapping him

We have an almost 19 month old daughter. He accused me of trapping him because I didn’t tell him I switched birth control. He didn’t consider me his gf even though we had been spending a lot of time together for the past 7 months at that time. So I admit I felt that as long as I was on something I was fine. Now I’m pregnant again, 13 weeks and he said he knows I sabotaged the condoms and he doesn’t trust me. We had a miscarriage a few months ago and it was very hard and I had told him I didn’t want to go through that again. So I don’t know why he thinks this. Sometimes I feel like he doesn’t want to take responsibility for anything. It always seems to be my fault....

I went to go use his phone and saw where he googled “Can birth control cause a miscarriage.” That was a little heart breaking for me. It’s like should I prep my own food?
