Sad That I Am Happy

I been feeling bad all day because me and my stepmom got into and it just messed up my whole day. So I went shopping which usually cheers me up but it didn't. Then I got a call from my ex-boyfriend today. First I didn't want to talk to him so I told him to call me back when my minutes were free even though we got mobile to mobile. So when he calls back I talk to him and we talk for like two hours. And I start to be in a better mood. The thing is I am not suppose to want to talk to him because he did me wrong. We go to school together but we stay like six hours away from each other. I had no problem with him talking to other females even though I wasn't talking to any one. A couple of weeks ago when I was talking to him I ask him if he was talking to anyone else and he got mad like that was a stupid question to ask him. Like a week later I call and when he answer his phone I could hear some girl in the background getting loud and stuff wanting to know who he was on the phone with. He was trying to hurry and rush me off the phone. I wasn't mad that there was another girl I was mad because he lied about it. Is that stupid? So anyway I told him not to call me any more and this is my first time talking to him since the incident. We talked like old times. I don't know how I am suppose to be feeling but it did put me in a better mood. How am I suppose to feel?
