Should I quit?

Me and my bf have been together for 1yr but I fucked up at some point when he travelled and I met someone but we didn’t sleep together and explained to him that I had a bf. My bf went through my phone and found the conversation but they was nothing much apart from morning and night text. So we fought about it and decided to move past it. This was about 6 months ago. I got pregnant and we decided to do the medical abortion. I was going through a hard time and he said he’d be there. The last night Before I took my last medication, he brought up the issue and started telling me how much he don’t trust and I’ll never be faithful and I don’t love him. He was just adding insults to injuries at the wrong time. This isn’t the first time to do this. Should I quit?
