I don’t know what to think

So I’ve been with my boyfriend a good while now and the other day he had to go to his ex as they used to live together and she had to move out as the tenancy was up and he had to go and clear it out. He text me later that night but wasn’t his usual kind of messages, they were short and not talking to me like he would have normally, I just put it down to he was stressed having to deal with his ex etc and I completely understood that. The next night he text me a long message and that’s when the doubts started. He has hardly text me since and I’m just hoping he hasn’t given up all because of this. This is the text he sent me and honestly I don’t know what to think. He has also been reading my messages but not replying.

Update just now. Been on phone to him and he’s apologised over and over again saying that he’ll never give up on me and that he loves me.
