Breakup! or Not??? Going Insane!!?

My boyfriend and I have been living together for about a year and a half and dating for a little over two years....and well to be honest our relation has not been the greatest and I honestly feel we are both at fault we BOTH want it our way!!! This is the thing before the holidays I made the mistake of breaking it off more because I felt that this is what he wanted and I had no other choice well doing it before the holidays just made matters that much more worse for me I am not to sure about him. Anyway I started to feel sad about the whole thing and well I asked him for us to give it one more try at least till I was done with school (one year) and if at the end of that it still wasn't working for him then we would part ways he didn't really want to do it, but agreed. So I put off my moving arrangements out of state on the back burner, but then when looking for a new place he brings up again that he doesn't want to sign a new lease ugh...at this point I don't even know what to say, I am a single mother with two kids living in Michigan and was trying to move back home to Texas so its a little nerve wrecking ending the relationship for many reasons don't get me wrong I do Love him and I do want it to work after he told me about not wanting to renew the lease I told him that he had two options move out now or really try to make this work without hesitating every other day, I dont want to live like that he says Iam giving him and ultimatium be that as it may I just want to be normal and without the drama I dont want to keep puting my kids through men and I just want to be normal please advise I fell like Iam going insane!!!!!......
