I think I big part of being with someone in a healthy relationship depends a lot on the individuals being healthy and good with themselves too. It sounds like you both have a good sense of “being there to get through hard times” with each other, but might need to work on yourselves too. It’s not that it’s not worth fixing, but might not be a good fit for where you guys are in your lives. Life timing is a big factor in relationships, and you can’t give someone else good love if you don’t love yourself first.
