He broke up with me...again.

Me and the kids went and spent Spring Break with him and his kids last week.  Had a blast really, took the kids on a few hiking trips, me and him hung out more than we had in a while, I had a yard sale while there and helped him mow some of his yards.  Things seemed to be going really well.  We've been needing to have a talk of some sort for a month or so and we started a few times but always got interrupted.  We talked little by little.  Made it back home a day later than I wanted to but that was okay.  I was convinced that things had changed a lot and was mentally preparing myself to move back this summer.  We talked last night and as I was telling him how much I missed him after being with them for a week last night he said that was my fault.  Preceded to tell me his part of our conversation that he wants this over.  He doesn't believe I will move back, that all I have been doing is playing games.  That all I've been doing is causing pain and that in his eyes I don't care.  I'm the one that's driven back and forth almost every month for the last year and half.  I spend the money on gas and the time it takes to drive 4 1/2 hours one way to spend less than 48 hours with him and the kids.  I've always been the one to let him know how much I love and miss him but yet to him they mean nothing.  He started school last summer and got accepted into a Respiratory Therapy class and while I was there at Spring Break he had a little bit of homework which he didn't get the chance to work on.  I would ask if he needed some time, as I would try to keep the kids calmed down or take them out for a while but he never sat down to work on it accept once and he gave up after 30 min.  He told me I am a distraction and he can't do what he needs to do while I am there.  I am completely heartbroken.  I was really ready to move back and was looking forward to it, especially after having what seemed to be such a great Spring Break.
