help!! ex bf

So me and my ex broke up about a month ago. It's been so hard for me to get over, he was good to me he did everything for me but was just a little controlling, but he made me beyond happy. I've b en talking to a new guy and he's really nice but he's kind of a jerk sometimes. I still love my ex but I don't know if it's a good idea that we get back together although he's been contacting me about it. I don't really know what to do at this point ?
