And you're in this relationship, why?

I would have a talk with her, tell her how you feel and ask her to change how she relates to you, to put you before her computer. I know how much I love my computer; both my husband and I are retired, come downstairs in the morning and instantly get on our individual computers but I always first (I'm second downstairs) go and greet him at his computer and ask how he slept. After a couple hours he goes and makes me breakfast, brings it to me at my computer and I make the effort and thank him for it! I give at least the minimum! Talk to her and demand the same; wouldn't occur to me to leave the house without mentioning it to my husband, telling him where I plan to go, approximately how long I expect to be gone, asking him if he wants to come along, etc.

It doesn't bode well that even when she is not on the computer, when she goes out, she does not even think of you! I don't think it's a computer problem, I think it's a there's-nothing-there problem. Who is able to totally ignore what they truly love, either thing or person?
