BF (23m) told me (22f) he does not see me in his future

My bf (23M) expressed his feelings that he does not see me(22F) in his future for the 3rd time. We have been dating for almost 2 years now. His main concern is that we have small arguments and fights all the time. He said that we do not understand each other’s povs or we are not on the same page. Me on the other hand, had been compromising, understanding where he is coming from and very accepting of his habits but I am also a very sensitive person.

Everytime I ask questions about this problem, his answer to almost everything is “I dont know” or “I’m not sure”. He stated “I dont see a future with you and I also don’t see the future without you.” So he doesn’t know whether to break up or not. He also mentioned that he is scared to be lonely when we break up. He is not in the right state of mind, what I see based on his actions is he is struggling mentally. He is showing signs of depression. If we are good, we are perfect but if we argue he will think that we are not understanding each other and its becomes a big argument.

TL;Dr BF (23m) told me (22f) he does not see me in his future for the 3rd time. Is he just mentally unstable to be on a relationship or are we not meant to be?
