Good Morning Kathleen,
If possible, try not to stay offended as each person makes these sort of decisions/sacrifices for one or another reason. Your friend at least should know that you've been loyal friend and that you're there for her to reach out if she wants to.
The other issue is that what you're expecting of her may not be something that she can do at this stage in her life.
Whether the care taking role is fulfilling to her or has other meaning i.e. soul agreement (her need/desire to pay back ME for something that ME had provided to her) or, her sense of commitment that defines her own role in her life now. The commitment in a way can also take away from her responsibilities to herself as an individual as well as those responsibilities or at least courtesy she can have towards you.
It appears that your friend either is codependent or feels some sort of an obligation towards ME. Whatever the cause behind it, it is not necessarily a rejection of you as a person or a friend. Perhaps she can't divide her attention to ME (like you said she gives her 24/7 care/attention) and you or others. As far as why she can't or won't divide her attention, she herself may not be even fully aware. It could be a subconscious drive to serve ME and to derive a sense of self (usefulness/helpful persona) through that.
Your self worth comes from within and not from what one person or even ME say or do. It is nice to hear that you're doing well despite external frustrations.
If there is anything else, let me know.

You've put it right - "each of us must live our life as we see it." You are really not in control of what they eventually do about it. And they know that. Friends are flexible without holding specific expectations of each other at all times.
Friendship love is not always expressed by such gestures (invitations or visitations) You've showed them your concern, you've reached out to them and you're still concerned about the two of them. Hopefully you're able to keep your invitations open should they decide to come over. If they chose not to, that too is their choice and you can respect it. Try not to compare yourself to others in their circle or the events/trips they engage in. Different friends interact differently with each other. That does not reflect that they prefer someone over you or are rejecting you.
