Hi there (((R Summers))) - it's me Bella from Q&A. I use a different unsername here in the forums. Sorry you ended up breaking up and yes it's normal to go through a grieving time. Just because he didn't fight to hang on doesn't mean he doesn't actually care for you - since he cried I think he does care. He may be one of those mild mannered kind of people who don't know what to say during a crisis.
I think you have the idea you want more passion and he's kind of low key. Just remember passion does fade somewhat and it takes work to keep it alive. As people, we also have to be careful not to have unrealistic expectations - for women it's the 'fairy tale' fantasy or termed the 'romantic type'.
In your other thread you mention how F was too pushy and you were put off by this, so you ended up finding a 'safe' person (M). You now realize that although you're not fond of a pushy type, at the same time it's kind of exciting and thinking it's kind of appealing. If you don't think this recent ex could fill that part of you, then you made the right decision.
I hope though in time, you both can still be friends. It won't happen right away, but hopefully later. Try not to take it personal about him not fighting for you - he might be having different feelings or is too hurt to say it ATM. Best of luck.
