Can it ever work with an ex....

My ex and I have had our fair share of ups and downs throughout the entire time we’ve known each other. We dated about 4-5 years ago for almost a year and ended up breaking up cause we just couldn’t seem to make things work. We ended up keeping in contact and “tried to make things work” aka continued to sleep together until he ended things and got back with his ex. We didn’t talk for a few years and began speaking last year where we realized we missed each other so much and the love we had never faded and picked up where we left off. I think we jumped into it too quick as we broke up a few months later. We’ve been trying to work things out for about a year. We have horrible communication, neither of us has ever cheated or disrespected the other in any way but the trust seems to not be there anymore. He’s said a few times that it’s time we should call it and it’s been a year etc but still wants to talk. He rarely texts me first, barely asks me to hang out but Gets upset if I don’t message him or talk to him. He tells me he misses me and still loves me but then why won’t he make the necessary effort to fix things instead of blaming me for why we aren’t working? I’ve never loved anyone like I do him and I can tell he feels the same. We just can’t seem to let the other go. I suffer from depression so it’s been a really hard year in general dealing with this and all life throws.

I came to glow because I’ve seen posts everyday where ladies are so supportive and caring towards one another and I’m looking to just get some advice of anyone who’s ever been through this with an ex, how it turned out, and if you think “ex’s are ex’s for a reason” or if you think things can work. Be honest but not mean lol
