Wait or leave...:/ confused..very ?

Ok so my ex and my have been texting about all day for the past two days besides when he's been working.. the night before I asked if he wanted me to still try n work things out n he said idk..so I stopped texting him and posted on my facebook thnks for making me realize I don't need you..after that he got all crazy and texted me telling me idk meant maybe and he didn't want me to leave and he wasted his time talking to his mom about it and she told him how to settle down and yeah..then he said he told me "to give him time" which he did but idk how much time is enough for a guy or how long I should wait around last night he said he was in a good mood cuz he had me then said now does that wanna make yu leave..I said no then he said good you better not be talking to other guys already..and today we've flirted and talked but idk what's up or what to do he says its not another girl and I pretty much believe that
