Search Results: getting him back

I am meeting with my boyfriend of a year who said we were on a "break" a month ago and ghosted me. During that time he hungout with this girl that during our relationship I told him he cannot talk to or we are done. They have done sexual things before and she sent me an extremely disrespectful text (disrespecting me and my boyfriend) 6 months ago. He wants to talk tomorrow (likely about getting back together). I really need either him to confess to me he saw her or I need to bring it up and clarify that if we do get back together he needs to cut her off permanently and he will not be going on "breaks" to talk to her every now and then if thats why he did this. His response to those needs is the deciding factor that is gonna make or break his chance of getting back together with me. The problem is this is his first relationship and he has a strong "fighting = broken relationship" thinking. And unfortunately I cannot bring up this topic without being mad and fighting about it. I was thinking of typing everything I want to say on a paper a bringing it with me and then being like "I don't know how to talk about this without fighting and I don't want to fight so please read this" and hand it to him. Would this be a good idea or weird/too much drama? Any other ideas? I just feel like if I bring it up by talking about it that it will lead to a negative conversation/fighting and I won't say the right things on the spot.

So I'm talking to 2 guys from a dating app.. READ ALL:

Man A: he was sending me hearts and saying my face lips are nice etc and he was kinda getting sexual so I said im a virgin and am waiting for marriage. He said he doesn't think he can wait. So I said well then lets cancel our date but you seam very nice so wish you all the best. Then now he text back and said he wants to meet and he will have to wait for me. Is he lying? Cause i not gonna change my mind its been 24 years I've said no so far I dont wanna waste my time or his.

Man B: Is older he is 9 years older than me. He hasent said anything sexual not evan sent heart. He wants to meet in town to walk around and look in fun shops/eat waffles. He has 2 cats he talk about a lot and he wants a family like me. He is very introverted which I like. I haven't told him im waiting cause he seams more ready to settle down.. I mean im 24 he is 33 and he wants kids so maybe he is serious or he just wanna have fun?

SERIOUS=Can wait until marriage/wants family etc basically settle down not trying to just have a fun fling.
