Girlfriend wants to meet beau’s ill, elusive mom.

Dear Amy: My boyfriend and I have been dating for a year, but I haven't met his mom yet.

We're both in our mid-20s and currently live near our parents.

This is a tough situation because his mother suffers from an undiagnosable condition that has left her homebound and unable to perform many of what we consider normal daily duties.

My boyfriend has told me many times that when he has approached the topic with her, she has been very interested in him bringing me by the house.

One time we even had set plans to do so and then she backed out a couple of days before.

I've spent a lot of time over this year being somewhat offended. I just can't help it.

I realize that she is going through something that I can't ever truly understand and that she is self-conscious about the reality of it.

I also realize that there are some underlying mental health issues that have been created because of her inability to leave her home or interact with others.

I hate feeling this way because I understand that she is really struggling, but our relationship has gotten very serious and I worry that I won't even meet her until our wedding day, if it gets that far.

I want her to know that I am very much in love with her son and that I care about her deeply, too.

I also want to stop feeling offended that she has made little effort to meet me because I know it's not completely her fault. Do you have any advice that could help me in this situation?

Dear Longing: You and I are both guessing about this woman's condition, but I doubt it is "undiagnosable." It is undiagnosed, however, or at least you haven't been told her diagnosis.

I also assume that her mental health issues are not a result of her isolation, but possibly the cause of it.

She might be agoraphobic, a hoarder, alcoholic, depressed or have any number of other health issues affecting her ability to meet you.

Whatever her malady, you are making a mistake to take this personally. She was this way before you came along and she may not improve without treatment.
