My boy friend said he's was done with me last night so we left it at that An this morning he was text me calling me baby an bay what does this mean? Because I really don't get it?

Your best bet is to ask him. We don't know this guy and his motives.

Yeah I also think you should ask him !

Were you in some sort of fight? If you were that could have been why he said that...

If you don't get it, I can't imagine how we could, not being there or knowing either one of you - but people change their minds all the time. Mostly they don't want to be alone, so they keep going back to fighting whether they like it or not.
If you both fight a lot, sit down and talk it all out at a calm moment. Or next time you will really might lose him.
