My man thinks I’m a liar

He texted me this morning who was ??? And saying I spoke to him when I was pregnant with our baby. Which I said I didn’t speak to him in a while and didn’t say when was the last time. He said we are done because I’m too dishonest and he can’t believe anything I say. I spoke to that guy while I was pregnant to let him know I was pregnant because I was once engaged to him and I knew it would hurt him so I chose to tell him so he wouldn’t find out from anyone else. That was our conversation and haven’t spoken to him since. My man really told me to move out our apartment. I feel like he’s right because I’ve always told white lies. I’ve never cheated. But I do keep things away from him because I know he’ll get upset. This keeps happening. I feel like my past will always come up. I sometimes feel like telling him every detail of my life before him but I know for a fact he wouldn’t respect me and leave me. Also I shouldn’t have to tell him everything. The only thing that matters is everything with him. Man I fucked up :(
