is he too young for MLC?

[WAS32]

I am trying very hard right now. We had a very good night last night and then this morning everything went wrong. He started R talk so I listened and validated his feelings but i have feelings to. he wants friends with benefits I think and I told him I couldn't do that. I can't just be his friend that sleeps with him. So we talked a little more amd it was getting us any where so I asked him to leave. He left really pissed off did something to his cell phone and when I texted him why he was keeping secrets from me on a text he sent back that we were over. He wanted to go to arbitration to find out how much he would have to pay me.

i asked him if he could talk to me about this and what was it that changed so fast? he is sort of texting me back right now and accusing me of the things he is doing. I'm not keeping secrets, he is. And about stupid stuff too. I am really confused today.
