Hello whoamihere: I believe I replied to another of your posts on this subject. So, if you'll bare with me, I'll just repeat myself here. From my perspective, I think the important thing is for you to do what you need to do to take care of yourself. Likewise, your fiancé needs to do whatever he needs to do in order to take care of himself. No good will come from either one of you sacrificing yourselves for the sake of the other.

One thing you can do is to look for little things to do for your fiancé here-&-there. You know him... so you'll have to figure out what these things are. From my perspective, you don't have to do a lot. For one thing, you probably don't have the energy to do so. And, also, you don't want to smother him. Just try to find a few little things now-&-again you can do for him to let him know you care & you're there for him.

The other thing here is, of course, to be available to talk, to the extent you are able. Often men are averse to talking through their emotions. So your fiancé may or may not want to do this. But also, since you're struggling yourself, you may or may not feel up to doing much of this yourself. So depending on how much your fiancé wants / needs to talk, & how capable you feel of talking, it may be important for your fiancé to seek out a grief counselor or therapist of his own (assuming he does not already have one.)

I wish you both well...
