Relationships..

I know this is kinda odd to put on here. But does anyone have advice for me? My boyfriend and I have been dating since December 12th and we almost broke up last night. He hasn't told me why he's thought about taking a break yet but I'm 80% sure that it's because I'm too controlling. I didn't realize how controlling I was until I took a step back and realized it. I just really need some advice on how not to be so controlling.
