Hi Heather Nann,
I will echo what Barbara Anastasia says above. The comfortable sock is probably what you’re really looking for, but you have lost some of the pizzazz that goes along with it.
Are you still dating each other? Are you talking about your needs? Sometimes shutdown is what we call comfortable. So if your needs are not being met, even if he is a great guy, it may feel a little stale.
XXXX is only one half of the equation anyway. You bring in the rest. The same is true of Cccc.
XXXX looks good because you haven’t had any fights and he hasn’t done any of the annoying or just normal but not familiar stuff that will drive you nuts later.
