HELP HURRY IT'S ABOUT MY BF!! (IMS?????)?

OK, Last Monday my BF came over to my house and he was holding me and saying he loves me and all of that fun stuff!! it was amazing!!! then on Tuesday we talked like always!! =) then on wednesday my cell phone broke and I didn't talk to him all day until that night when he called my house and I missed him SO bad all day && I told him that and THIS IS HIS NORMAL PERSONALITY WHAT I'M ABOUT TO SAY... aww, I missed you too Baby, I love you so much, I wish I could come see you honey, you're so special to me. <-- that is how he USUALLY NORMALLY 24/7 acts around me... But Thursday was bad... I was testing him on my dads phone late at night and he said he would call me at like 11 or 12 whenever his baseball game got over and then I asked at like 12 where he was and he said at his buddies house cause they were celebrating winning and then I asked him if he could call me later and he said no. and I asked why and he said cause I'm here. Then he said he'd call me in the morning when he woke up to say he loves me and then it was Friday like at 2 and his friend turned his phone on and was acting like my boyfriend and then he said If I was Colin, I would break up w. you. That kinda took me by surprise cause I didn't really do anything...??? to colin or his friends. Then he called me [Colin] and started saying how he doesn't love me and everything... Then I went out with my family to get my mind off of him and my phone died so I wouldn't have to talk or text him and he was just being a jerk. Saturday night when he got back he called me and asked me out again and hesitiating I said yes. But then he was being somewhat nice again. and sunday we were jokin around and everything. Then I said something (cause I thought it was cute and I was dropping hints) about real-world and how this girls bf wrote her a list of things he likes about her and how he should do that for me and Colin said Im not like that...Sorry. And then I SAID OK but I KNEW he IS like that... he has done things like it before. Then I started crying cause I've felt worthless these past couple days to him. But then I just called him and said you have to be nicer or I'm going to leave. and he wouldn't say anything back (on the phone) so I just hung up. He didn't call me back. So I wrote like 3 songs and sent them to him in text message and he actually thinks that we are broke up now. and before when we almost broke up he was calling me constantly and saying he loves me and omg it was like I LOVE YOU COLIN!! and we were over it. and when we would get in fights I could say sorry and that would be the end of it. But he just snapped overnight... he HAS acted this way before and I looked up IMS - irritable male syndrome - how long will it last and will he be the same guy agian
