Hi, for context was together for a year,split up which was his decision and out of nowhere. Didn't speak for around 6 weeks. Got back in contact, saw each other now and again. A couple of months later he said what a mistake he mad etc so started dating again. Has been hard for me given what happened previously him ending etc. lately we've had quite a few big arguments as I've felt lack of effort and I suppose my insecurities of the same thing happening again. We've agreed to carry on and try and do things differently etc and I've said I'll move past what's happened which I really want. He's said his struggling to get past the big arguments and his feelings are still there but not as strong now due to the arguments but he believes they can grow. Do you think I'm holding on to false hope? How can someone's feelings just change like that?
