losing love

I love my partner but I feel like the love he has for me is gone, he does things that I’ve mentioned bother me and he continuously tells me he’ll change but when he tells me something I do bothers him I do my best to change yet it seems so hard for him to do the same and he says its “how he is/grew up” I know change doesn’t happen overnight but I feel like Ive been waiting for something that isn’t going to happen. I don’t know if I just have an unhealthy attachment to him or if I’m over reacting. Please help me
