She has no reason to be mad right?

Me and this so call girl. been off and on for a while. I just text her like 10 min ago.. she was talking about how she went to six flag ect. ect. and how she wish someone went with her. so I was playing and said why didnt you think your boyfriend ^_^....

she said he was at his mom house. I thought she was playing. then I found she wasnt. so we start fighting. am just saying tho. She kept me believing that me and her. could have a serious relationship. then come to find out. she dating someone else. so am going to guess that serious relationship crap was a lie. by that time I was Really mad. so I start cussing ( not calling her out her name). I told her like you shoulda told me sooner. you didnt want to be with me. it Mess up how you kept me believing this crap. she really believe I need her. I was fine before I met her! ill be fine when she leave.Am done with her. She was like the only girl. that I really love. BS like this happen. I dont need to be dealing with crap like this. When her punk boyfriend leave her. I wont be there. she alway trying to get mad about some crap.who think she got a reason to be mad? I mean I think it her false

shee really should've told you ,
thats straight up rude .
