Just looking for advice really..
Been with my partner 4 years, due to marry next year and have a 20 month old.
The last year or so we’ve really struggled, I’ve found myself constantly asking if he’s alright because he’s so miserable. He’ll often forget things to do with me and my daughter, but can remember everything to do with the gym and work..
We’ve gone back and fourth about going out separate ways because he just won’t hold his word about making an effort. This time he lasted 2 weeks and went back to leaving crap everywhere and not even giving me a second look.. he said this morning he thinks it’s best we go our separate ways because we always end up at square one. I clarified that saying it’s always him that just stops trying, and he said “alright, I can’t do it then”
I’ve been an absolute mess all morning, I know the best thing is to leave him because im scared my daughter will realise he’s a bad dad when im no longer there to remind him of everything.. but it doesn’t stop the tears
How can I try and be positive about this? I couldn’t imagine my life with anyone else that’s why I’ve tried so hard, for so long. I’m absolutely heart broken, I don’t want to be lonely 
Thanks everyone x
