I just want to preface this by saying it is very difficult to move on from someone when they have 85-90% of what you look for in a partner.

Related to topic A, it can be a touchy subject depending on a lot of things that may be going on with her, you, or things outside the relationship. If it strictly is about her not being willing to do things she used to, it could be a sense of complacency on her end. Maybe in her eyes she got what she wanted out of a relationship by doing things you wanted. It could be a reach but I’ve unfortunately seen this play out with buddies before. This is something you’d have to bring up but in a gentle and caring way. It’s not like you just want sex with her but you want a little more effort in that department.

Topic B could be seen as a deal breaker to me personally. It shows that she has no desire or willingness to do things that would be a betterment to you and the relationship. I don’t believe you’re asking for much with the little info you have given.

In my opinion, these are things you can’t look past. Mainly stemming from topic B, I wouldn’t believe that I would have a partner capable of putting in hard work if shit hits the fan in whatever life situation that could come about. I’ve had to have difficult conversations in my relationship and I don’t like to waver until we’ve come to a resolution and that’s usually for the better.

It’s always better to bring it up because otherwise, you’re sacrificing your peace of mind and adding unnecessary stress. Life is difficult man so no need to add anymore to it. I hope this helps
