You will help him by repainting the bed room (with him) and changing furniture around and motivating him to start to sort thru her things. (Better if their in-laws contributed to this, it’s area of the grieving process)
Shanhun, I am able to know how you’re feeling about that relationship and just why you’re wondering whether this has a long-lasting future.
But I do not think you might be, after all, wasting your own time with this specific guy, with him, you say you love him, and you can even imagine spending the rest of your life with him because you like being. So long as the partnership has those strengths, and it is satisfying in today’s, simply enjoy being with him. None of us understands just how a certain relationship will come out in the foreseeable future, and also this one does not seem specially dangerous, or perhaps a bad bet.
It is good that this guy enjoyed their spouse, and that their memories of her, along with his wedding, are good people. Not just does that declare that he is perhaps maybe not saddled by lots of shame and remorse and regret and unresolved conflict regarding their spouse and wedding, it implies that his grieving process may be quite a bit easier and long than it may be if it are not the situation.
