Lil, I am so happy to read that post. Finally, you have achieved peace of mind and acceptance after attempting to fix things for so long. You've been running on empty for a long time now, since the death of your H. The break has indeed been a blessing.
Your bf, whom I will now call TS ( well, you said he looks like Tom Selleck) is going to be going through a lot of changes as his mother's illness progresses. Resist the need to steer the ship: Remain in passenger mode, where you can go about exploring the ship, admiring the view of life, etc. ( Well, at least it isn't an animal or food metaphor). Think of TS as a fellow passenger, who not only provides companionship, but who can cook and build shelves and such as well! And it does not hurt that he is handsome ( a 4 has to think of these things, lol).
Who knows where this ship may eventually head, anyway...allow yourself the freedom to enjoy and have FUN! ( But not too much moving around fun just yet until the ankle is stronger).
