Is he preparing to break up... ?

We have been arguing quite a lot often, but we always end up sorting it out and being fine again. Our arguments are really silly like why didn't you do this or that. Anyway -a week ago, he legitimately told me it was over and he was tired, but after a lot of crying we solved things up. However today, he made me watch a movie with him like for real (he never does that) and he made me turn off my phone and just sit there to watch it. He put on a sad movie and to sum it up it was a man who suffered a lot, lost everything but with presistance and positive thought got back on his feet. After the movie he was weird and told weird stuff. he said "i wanted u to watch this movie bcus you are not very positive and this is eye-opening for you - I want you to know that sometimes things go dark, but it gets better, i want you to think that when..." and then he stopped and changed saying "for example if u get rejected by the college" however I had the feeling he was going to say "when I break up with you" or something similar to that.. I mean I'm 85% sure that's what he was going to say... then we had dinner and it was weird, he was quiet and giving me fake smiles...
