Search Results: telling boyfriend the truth

Hi so I've been struggling with an issue I can't quite figure out. I found out when I got back with my ex boyfriend that he had slept with his old ex. On top of that, I learned he hung out with a female friend and that she had flirted with him. Automatically, I panicked thinking she was another girl he had slept with. I asked my boyfriend if I could meet her, and so when he said yes I reached out to her and she didn't reply and told my boyfriend. I let it go, as I realized my behavior was kind of weird even tho I just wanted to know the truth. My boyfriend kept telling me no they didn't do anything over the next few months, and I was still bringing her up and accusing him on and off. One day I talked to him about it and brought her up again. He asked me if I had gone and asked her if they slept together, and I said no and asked him why he said that. He responded by telling me that I had told him I was going to ask her myself in the past, and so he thought I had and also because I had been bringing her up nonstop. He said that nothing happened, that she didn't tell him I said anything, and said that she would say no if I asked her myself if they had sex. Should I believe any of this?

Me and my ex boyfriend broke up 4 months ago (he ended it because we fight too much and he thinks im too demanding)
But we are still "friends" since he still contacts me every week (messages and calls me) and wants to hang out every week - he's always the one initiating everything
I still love my ex boyfriend
Last night my ex boyfriend called me and I exploded.

This was our conversation:
Me - i need to ask you questions, but first im gonna be honest, i feel awkward just us being friends, tell me the truth, do you see us in the future or you dont think we are right for each other?
Him - its not that, i really do want to be with you but the reason why i broke it off is because you are just too demanding, im pursuing my career as a police and im really serious about it so i can't give you full attention and a lot of time, i wish i could be with you, i really do but i just need time to do this on my own
Me - i just dont want to be played around or you putting me in the back burner. I rather move on and find someone else
Him - playing you around? Are you serious? How am i playing you around? Im not seeing other girls. Im not talking to other girls. Im focusing on myself. I've been single for a while now and if i wanted to flirt with other girls, I would have. But im not. Why do u think i message you and call you often? Why do u think i wanna hang out with you? Seriously, you always doubt me. You give up on me easily too.
Me - what if you find someone better? What if u meet someone in the police academy?
Him - omg no. If im in a commited relationship, i would not do that. And plus im not there to meet girls. You just dont understand me. Give me a chance to do finish this please. If I've already completed this, I would have never left you. You know what? Lets just meet in person this weekend and talk about it okay? Its better to talk about it when we see each other. Dont think about it too much for now okay?

Why does he want to talk bout this in person rather than just telling me on phone?
