Just on a bit of a rant for advice could be too long

I'm so confused. Men confuse me totally. Run down, short version lol. Met my daughters dad last year, where together for 6 months I got pregnant after 3, we broke up after 6. Now our daughter is 1 month old, and he's back on the scene. BUT it was he who stopped talking to me in September for no reason and never contacted me again. Yet now that he's back he started being really flirty really really flirty, making comments of us being together again, then after an argument two weeks ago, when I then said there was to be no more of that talk between us it's to strictly be about her. He said okay have it your way whateve you want then. Strictly business. Then cancelled seeing her, two weeks in a row, second week he just didn't contact. So finally I cracked and give off about it and he came back again apologising and again he's making hints of us being together!!!! What is he playing at with all these wee games. And that the min I say it isn't about us keep it about her, he then doesn't want to know her.
