My friend's relationship, a problem or just normal?

[AlethiaSi]

Ok, so my friend has been dating this guy for a little over a year, at about 6 months, they moved in together and things were going well. However, the past 6 months or so, they've had a lot of money problems and have been fighting a lot.
In addition, they don't have sex very often, like, once a month or so, and she always has to initiate it. This has been a "problem" since they got together, but she has just let it go, she says he's just not a "sexual" person... Ok, fine (the guy is like 25 btw).

So, the money problems are finally better and things are going relatively well. The other day she got into the shower with him, and he basically ignored her, didn't get a hard on or anything. As she puts it he just kept washing his hair. She feels really rejected now and is thinking about breaking up with him (not just for this, but for basically everything).

My question to all of you is what do you think of my friends situation? Is this normal? Should she expect more?

*I didn't really know what to say to her, and I don't blame her for getting upset, I just was wondering what other people thought about it.*
